I don't capitalize on my atheism, nor do I deny the possibility of deities existing. This is what the majority of atheists are like. But of course, we aren't as vocal as those on the more extreme ends. I would rather you not think anti-theism is the norm, because it's not.
I think you must be referring to the Christian god specifically, because I find most Norse gods to be pretty selfless and kind. I have no issue viewing the act of killing everything because of an easily prevented mistake, and sentencing beings to eternal torment on the basis of belief, of all things, to be horrendously immoral. I wouldn't do that even if I had the power to do so, I don't even do that it SIMS games where I do have the power to do stuff like that, and those creatures aren't even real.
But, what makes you think morality has anything to do with belief? I don't believe in the Christian god due to lack of evidence, not because I disagree with its behavior. It's behavior is irrelevant. I don't find murderers moral either, but I never doubt that they exist, thanks to the evidence for their existence.
Also, what "some people" say, I don't agree with, for if there is no god to put pieces into people, then obviously we wouldn't have a little bit of god in all of us.
