First, define "evil".

Evil: an action taken based on an unquestioned belief.

Suffering isn't evil. Causing suffering for imaginary beings is.

God, by definition, doesn't exist. "Super-natural" means "outside nature", and "nature" is everything that is real.

Ergo, Christianity is a nice group hug when it works, but then the group breaks out into individuals that go to work at Competitive Dumbassery, Inc and proceed to kill everyone 'efficiently.'
