Thank you for this conversation.
I agree about the definition of evil, except that now we need to define "pain". In the US right now, we have a very large movement to include "hurt feelings" as pain that should be illegal, specifically legislation is pending against hate speech. I consider any laws passed that would make hate speech illegal an unnatural action, but laws that make bodily or property harm illegal as natural.
What do you think? Where should the line that forces a type of behavior be drawn?
