Evil and bad people usually have actual reasons for why they are doing bad things. They aren’t doing bad things just to do them — there is usually something bad that happened in their past, etc
No. They might have reasons, but passing on violence and pain to others is never justified.
If it's justified for one person to bully another because of trouble at home, then the other person is justified to hit back and so on. That's how you get blood feuds. Dumb idea.
