For example, in The Shield, the cop character Shane is super racist and says the N-word, but when a Black girl is killed, Shane gets really mad and wants to find and kill the killer or bring him to justice. Some CEOs who are straight-up classist would still help their employees, and if their employee dies, they would start funds for their kids. But why? Why would people like this do something ‘good,’ especially when there isn’t anything in it for them?
Each person has a different definition of good. On a Venn diagram, you might even overlap with Hitler or pol pot on one or two points. Humans and their ethics and morality are complex. Different people have different dealbreakers.
Take the example of “even a broken clock is right twice a day” and therein find an answer.
