"That vengeance is good, and that people must earn their love, and that the strong will survive."
The strong do survive. This is nature. This is evolution. And people must earn their respect (not love - respect). I do not give respect to a person who murders innocent civilians. Do you?
"Very much like atheism yes"

"Is it possible that this is so christians will think all athiests are evil? I know I'm beating a dead horse with this issue, but I read it SOMEWHERE, and I can't shake it."
Christians have, though mroe in the past than now, used Satanism to symbolize all those who do not believe in God.
