What is evil?
I am beginning to think it is simple disregard for others. I was talking to a friend recently and we were discussing that our asshole humor was not understood by others, but that we were still genuinely nice guys inside. Then i realized that my “kidding” style when used by other people to me made me hate them. Finally I came to the conclusion that many times I have unintentionally been a bully.
I think much evil and cruelty in the world might simply be traced back to a disregard for others.
