It's a universal truth that you can always count on evil people to do what evil people do, hence the reason they're called evil.
You know, this may make sense at first glance (blame all your problems on “evil”), but it tends to quickly fall apart when you ask them to define “evil”.
Evil is a very subjective term (possibly the most subjective there is), after all, and it’s likely no two people have the same definiton of “evil” (and most don’t even realize that). It’s easy to shift all your problems onto “the other” and call them “evil” (which is how the Nazis demonized the Jews, how the Crusaders demonized the Arabs, how incels demonized women, and how Trump demonized everyone that isn’t a fascist StormTrumper(*)), but that reasoning is ultimately self-destructive in nature. After all, if there is (eventually and inevitably) no more “other” to blame, people will start turning on each other like rabid animals in a desperate attempt to find another scapegoat. Which we saw once Trump himself became “the other” to most of his followers by getting a booster shot.
TL;DR, stop calling things you don’t like “evil” or “sinful” and actually start explaining why they’re (supposedly) bad with cold hard logic.
(*)how the Jihadists demonized all infidels, how the Kims demonized the West, how Darth Sidious demonized the Jedi, how T’Kuvma demonized the Federation, how Radovid demonized all mages(**)… As Futurama made clear with “Fear of a Bot Planet”, incompetent or corrupt leaders will always find someone else to blame to keep the unhappy populace from turning on them.

“How do men deal with fear? They seek reassurance... and scapegoats. The Church of the Eternal Fire understands this perfectly. And so it promises to improve the lives of its flock by pointing out the guilty. Who started the war? Who profits from it? Why, it's obvious - mages, elves, dwarves. In a word, any and all deviants.” - Witcher 3
