"necessary" could mean something that must exist, could not be otherwise. like, uhh, the sun? idk man

"evil" is just the dregs of Abrahamic thought that plague our culture, though

it's definitely a dumb question but fun to play along with if you don't take it too seriously

Ok Doug

I don’t think though, that for the goal of living a happy life, any harm is theoretically necessary.

Whose happiness are we talking about? Surely if one person's happiness conflicts with someone or something that already exists, they can't both have happiness and harmlessness. (Also, what are you considering harm? Just harm to people? What about animals? Plants? The planet as a whole?)

Modern human life is inherently very harmful to a wide range of things.

Jordan Peterson, is that you? 🙃
