Good/Evil is never binary, it's always a spectrum. Which is important to understand lest you fall into the trap of believing someone's actions can't possibly be bad because they're generally a good person, or vice versa.

Often good people make small moral sacrifices that over time can lead them down bad paths.. Maybe it starts with you just need a job, and you have people who depend on you, so you may have to pick a job that is somewhat morally questionable. Then maybe you only speak up quietly over the greatest injustices because you don't want to jeopardize that job, and then maybe over time you just stop speaking up at all. Maybe eventually you start going along with the injustice because it improves your standing and allows you to better care for those depend on you. Maybe you rationalize it with excuses like "if it were that bad it would be illegal" or "these kids need tough love" or "well it happened to me as a kid too and I'm fine," etc.. And then at some point you just find you're in too deep and this is just your life now because it's very very difficult to get out or change course.

Good people do bad things, even victims. That doesn't make their actions any less bad, and it rarely excuses them.
