When people do whatever they effing well like because they say there is no God/afterlife.
Everyone does whatever they effing like already. How old are you? Are you a young, naive child? I think it's more likely you live in a little cultural bubble full of people reinforcing the delusion with attitudes like "atheists have no morals" and other inhumane delusions so typical of social dominance religions like yours supported by cognitive bias and lies.
Let's educate you. Religion doesn't stop anyone doing whatever the eff they like. It might make them suppress something, which will inevitably express itself, and often in very humiliating ways. That's how suppression works. Religion is really good at influencing people to suppress a ton of their humanness thinking, I guess, that it will just go away? Guess what? It doesn't. It just gets twisted and pissed and will get its revenge on you, as we so often see among religionists who worship an ideology. They worship being right. But that doesn't stop them doing whatever the eff they like regardless of how many lies and pretenses and secret logistics it takes to feed the urge but still maintain the social conformity veneer. This is probably why people in religious societies like porn more than the rest of us.
Religion doesn't stop crime. It doesn't stop mental illness or physical illness. It doesn't make anyone a better person. Oh, I know there's people who say it does, but show me such a person and I'll show you either a liar or someone who is a better human than their own religion can recognize. Their own confusing, absolutist, incoherent, authoritarian, inhumane, ignorant, irrelevant "moral code."
But what religion DOES offer is extra layers of bullshit and hijacking of human minds through their reactive animal brain and sense of self preservation. You must be so proud.
When Christians say they rationally choose their religion (which they don't, not consciously, not rationally, no) are only saying, "I don't give a shit about truth and I've handed my conscience over to an authority other than myself, so I'm also not accountable for the consequences of caring about ideological identity more than about truth or human beings or anything else really except feeling like I'm right about bullshit I've never questioned even once, but rather going to my pastor or whatever mouthpiece gives me my truth because I'm not capable of figuring it out for myself and don't want to try."
Your religion is based in cognitive error, but I don't expect any Christian to even be curious about that much less actively try to find out why. They don't have the wherewithal to even be embarrassed at the sheer stupidity of organized religion, but that's an easy way to live when millions around you won't question, either. Very easy to not even
learn to question.
So yeah, you and all your religious friends are no more controlling your own potential for evil than anyone else. In fact, dogmatic, absolutist, authoritarian religions like yours serve to diminish crucial skills and traits that could help you be a better person on your own, without needing someone pulling your strings and forming your own thoughts for you.
Why don't you name one good thing in the entire human universe that can't be had without religion. Still waiting for the "faithful" to answer that one.
By the way, we don't prosthelytize. We call out inhumane ideologies, most of which happen to be attached to superstition and magical sky daddy beliefs. We speak out against the beliefs and attitudes that might not harm the bearer, but every one of us contributes to the whole of society, and your religious beliefs contribute zealotry, extremism, terrorism, abuse, ignorance, and war. Im sure YOU don't have to be affected by the consequences of that. At least, not yet. Even when your beliefs hit the brick wall of reality, there is always some "plan b" excuse for it. Never questioning. Never brave enough to chuck the whole thing and start again. Maybe you could start by chucking the belief that developing your own conscience is a mortal sin.
