Why It Is Not Too Late To Repent And Turn To Christ

[Esquilax]

Who decides what is right or wrong?

Reality, and the predictable reactions human beings have to stimuli.

What if a person feels it is perfectly ok to kill someone and claims he is going by "survival of the fittest?"

Then he would be drastically unclear on what survival of the fittest means as a concept. So are you, I'd say; "fittest" doesn't mean "strongest," it means "most embodying the traits most conducive to survival." It's "fittest for survival," not "physically fittest." Human survival has always depended on our ability to cooperate and cultivate societies, and so anyone murdering on behalf of survival of the fittest is just factually wrong, unless they're a shark or something.

What if I go around claiming I'm an atheist, does that make me an atheist?

No, your beliefs dictate whether you're an atheist, not your claims. Ditto theism.

And if I then say or do things contradictory of an atheist does that mean all atheists have a bad rep? Hitler said he was a Christian, but his actions and life say otherwise.

Look, I hear this all the time, and it's no less true from you than it is from anyone else; christianity is a position of beliefs, not actions. If I checked off everything you thought made a good christian but didn't believe in god, would that make me a christian? No, it wouldn't, because christianity's baseline premise involves belief, and not a set of actions.

Your kind keeps saying that Hitler wasn't a christian, but you're wrong; if you had any interest in honestly portraying what your religion is, you'd just say he was bad at being a christian, instead of watering down your own position.
