So, what’s so terrible about atheists again? ............................................ They’re not Jewish or Christian is my guess. I’ve known several, they were never a threat to anyone. Actually they were very peace loving and behaved like most other religions should. I personally don’t measure people by their religious label, I measure them by their deeds. If a person is evil, they will show it, if they are good they will show it. You don’t have to be religious to love your fellow man, if goodness is in your heart.
It is when you start making your own calls of “good” and “evil” based on your gut, or your reason, or whatever that one starts to cross into “evil.”
The Communists thought they were doing good by killing millions. Ditto the Nazis. They decided that what felt good was good.
THAT is the path to the most heinous evil.
