People committing genocide also presumably don't wake up saying they're going to be evil again. Being able to justify an act to yourself doesn't make it not evil.

But then what does make something evil? Nature clearly doesn’t distinguish good vs evil. We humans do.

No. It’s the exact same question. Good vs evil are created in your head. Unless you believe in God or something similar.
