"It is also not unusual to find it more difficult to avoid Evil when everyone around you is treating those Evils as normal and mistreating anyone who refuses to participate. I think it would be a good idea for you to try to avoid falling in with another group like that. But — it isn't always possible, sometimes people who seem perfectly fine in most contexts will turn out to have fewer scruples about how they treat their enemies.
There isn't one single strategy that will work for everyone in scenarios like that, but — many people find it helpful to identify specific behaviors, like torture or rape, and commit themselves to avoiding those behaviors no matter what, even if it feels like a good idea in the moment. Some people find it helpful to imagine situations where someone else is trying to persuade them to do Evil, and specifically imagine themselves refusing, so that if those situations do happen it feels more possible to refuse. Some people find it helpful to have a trusted friend who they know would not countenance that sort of thing, and speak with them regularly about what they've been doing, so that they always know that if they do something gravely Evil they would have to admit it to their friend. Some people find that some avoidable scenarios make them much more willing to do Evil, like drunkenness, and those people should generally avoid whatever it is that makes them more willing to do Evil.
...some people also find it helpful to keep in mind that — it's not really doing your friends a favor if you let them pressure you into Evil. Convincing another person to do Evil is itself Evil. The best thing to do, if you could manage it, would be to talk your friends down from torture. Most people are not good enough at persuasion to do that, and it's not Evil to be unable to convince them, but joining in isn't just worse for your victim, or for your own soul, it's a little worse for your friends' souls too."
Pause.
"Were there any cases where someone tried to convince you to do something Evil, where you thought they'd make fun of you or similarly mistreat you for refusing, but where you refused anyways? And if so, what made those cases different?"
