“Not defending the beliefs of the atheists, but I have a few atheist friends who will object to equating their belief with ‘evil’. Just sayin’.”
There are agnostics, who don’t positively believe in God, but don’t disbelieve, either. And then there are atheists who positively believe God does not exist and teach that doctrine. To the extent the atheists attempt to or do convert others to their beliefs, yes, I’d say they are evil.
Agnostics? Maybe not so much.
Atheists ridicule the concept of faith, but the belief that there isn’t a God, is every bit an act of faith as in believing there is one.
