It made me wonder, hearing from certain people who faced discrimination and harassment. They were hurt every single day intentionally and some of them had PTSD caused by their harm and became incredibly jumpy and traumatized.
Would that make the person who caused the harm evil?
In my opinion, in order for an action to be evil, the actor must know what is good or what is right behavior. While sometimes the actor acts with intent to cause harm, sometimes, the actor is ignorant of such things.
What if they acknowledge it’s wrong, but it’s not when they do it
It is not about acknowledgement, it’s about understanding the morality of the action. Most of the time, only they know the answer to that question.
