The absolute first thing is to establish the jurisdiction of this scenario. The answer will be vastly different if the jurisdiction is California/USA than if the jurisdiction were South Susan. No shade against South Sudan, but we are talking about criminal and civil law, so the details might be very different.
But supposing this is a jurisdiction that follows in the Anglo-American common law (such as California, and I’ll proceed using California as the setting), then we can make some generally-true statement, some of which confirm what you’re already written:
- Criminal law exists to punish bad acts committed against society at-large
- Criminal law can only punish the persons or entities which have committed an act or omission that is proscribed in law, and only those persons or entities within the territory
- Dead people or dissolved corporations are beyond the reach of criminal law
- The notion that the next-of-kin will “inherit” the criminal liability was abolished long ago; see US Constitution “Bill of Attainder” prohibition, and equivalent in other jurisdiction like the UK or Australia
- Anyone that is still alive and collaborated to aid or supply the dead assailant can be pursued using criminal law or civil lawsuits, or both
- In parallel to the criminal law system, civil lawsuits can be filed against the remaining property of the dead assailant. This is known as the “estate” of that person, and the lawsuit would be captioned as “XYZ v the Estate of [dead assailant]”
- A civil lawsuit can only win as much property as the respondent (ie person being sued) has, or any insurance policy they had which might apply, or any debt which was owed to the respondent at the time of their death.
- Mass murder commonly result in civil lawsuits that do not obtain anywhere near the full amount to compensate for the victims’ families’ loss.
- As a result, the target of civil lawsuits can be expanded to include adjacent parties, such as the manufacturer of the weapon or materials used, under a claim of product liability or something similar. This is not a guaranteed result, but they often have deeper pockets and good insurance policies.
- Civil lawsuits can only bring a monetary compensation. The law cannot revive the dead, cannot erase or amend history, and cannot salve the void left when victims are removed from this world unjustly.
With all that said, the entire line of inquiry into the dead assailant’s will, or to their parent’s will, or anything like that, is entirely inapplicable. Children or parents do not inherit the sins of others, at least where criminal liability and civil lawsuits are concerned. Unless, of course, the parents participated somehow or willfully neglected a duty to report (very few of these exist in California, unless the victims were undoubtedly known to be children; see mandatory reporting laws). Thus, these other people cannot be sued nor criminally punished, usually.
The other commenter correctly said that what we call the “justice system” is more accurately called “harm reduction”. That’s not wrong, but I would post that the crimimal law system is about harm reduction (nb: I do not endorse the carcereal state of imprisoning huge segments of the population, disproportionately by race), whereas civil lawsuits are about equity and compensation.
Both systems exist in tandem to prevent people from achieving a bloodier form of justice in the streets, like in days of yore: pistols at dawn, dueling in general, lynching, “bigger army” diplomacy, shakedowns, midnight slaughters of whole families, and other such unpleasantries. It’s definitely not perfect, and it needs reforms in many parts, but the structure serves a purpose and so far, it’s what we have and the best that we have.


When looking through the history of Windows, some of the major milestones included the very concept of a windowed user interface in 3.1, refining the concept into a complete desktop-oriented (as in, a physical table top, with files and folders and a recycling bin) experience in Windows 95, huge backend improvements in the kernel (eg networking) by merging in the NT kernel (last used intact in Windows 2000) and giving us Windows XP.
Note well that XP was the first juncture between a consumer-oriented OS (a la Win 95/98) and a business-oriented OS (a la NT Server or Windows 2000). The missing link here is Windows ME, which was the next consumer OS after 98 but it flopped so hard when it became apparent that this artificial consumer/business division wasn’t going to scale. Specifically, the Windows 9x kernel had too many DOS-isms whereas the NT kernel had no such issues. Hence, Microsoft undertook the massive effort to bring the two kernels together for XP.
In that sense, XP coupled a newer kernel with a polished UI. In essence, the company bet all its chips on XP. And fortunately for them, it paid off. But this came with a cost: XP has to carry the lineage of both the DOS/95/98/ME and NT/2000 into the 21st Century. This means the same OS has to support things like Active Directory (a feature only used by corporate customers) and Fax for Windows (used by anyone that wanted to use their dial-up modem for faxing, but also on fax servers, which are somehow still relevant today), while also supporting DirectX for the consumer gaming segment, plus multi-user support for “home computer” customers that still share a single machine for a household, despite a market trend towards personalized computing, and everything else under the sun.
And that’s before we get to some of the backwards-compatibility support they still have to upkeep, like 32-bit support on the x86 family of CPUs, and BIOS (in spite of UEFI being a decade old). Notably, Windows on ARM has never kept such backwards compatibility, with ARM32 being completely deprecated and only ARM64 being supported by Windows 10 and beyond (hence, Windows on Raspberry Pi).
And then, of course, the Microsoft own-goals and mistakes: somewhere around 8.1, they decided to meet the tablet/touchscreen market by having Windows be touch-oriented. But as was blitheringly obvious then and now, the desktop concept cannot possibly be similar when the controls (keyboard/mouse versus touchscreen) are swapped out. Thus, this compromised the desktop experience in pursuit of a relatively niche target market. Meanwhile, Apple essentially forked their Mac OS to support mobile, tablet, and smartwatches as iOS, and aren’t exactly itching to merge iOS back into the desktop OS.
A better execution might have been to port Windows for ARM (which is what most/all phones and tablets use today) earlier than they did, use that as the basis of a tablet-experience OS (like how Windows Media Center was just an application atop Windows XP), and then later introduce compatibility with desktop apps (like how Apple can now do full-speed x86 emulation using special ARM extensions baked into their custom silicon). That said, the latter was only technically achievable in the 2020s, but seeing as Microsoft was the market leader well into the 2010s, they would have been in the same position as Apple is in today.
So to summarize my long-winded comment, Windows carries a lot of weight. It is the result of successfully merging two very-real market segments into one product (business users and consumer users), then MSFT dropped the ball by chasing the Next Big Thing and adding more diametrically-opposed objectives to an over-burdened OS, with nary a plan for how to eventually relieve it. Had they instead did a separate OS for tablet and mobile (rip Windows Phone), they could have merged that one into the XP-based kernel and got the refined best-of-both-worlds.
Instead, they now have the worst of both. The Windows 11 desktop experience sucks, with bad icons, near-invisible text boxes, confusion where there wasn’t any, and all while pushing consumers towards web browser-based apps. And to make it sting harder, because they’ve been feeding this mess to their corporate customers, those customers now demand that everything be kept the same (“better the enemy that you know”) which prevents Microsoft from making XP-level wholesale improvements.
They’re stuck, they know it, and they can’t really fix it unless great leadership shows up to take command of the ship. But similar to Amazon (which makes most of its revenue through AWS, not selling/shipping products), Microsoft makes the majority of its revenue in two segments: Azure cloud and Office 365. It’s hard to revamp Windows when it’s now playing third-fiddle.
(I’m sure I’ve got some of the historical details wrong, but it’s Saturday morning so full send)
