You're still missing my point. The exact religious motivation is ultimately irrelevant for the topic I was getting at, it's more referencing the idea that most people tend to argue their religion approves of the things they already approve of and disapproves of the things they already disapprove of. Religious law becomes confirmation of their own biases rather than a clear change from previously held moral or ethical beliefs. This is hardly confined to any one religion. This is important when we consider how people will act without religion because my argument is that people's overall morals won't change much when we take out the middle step of religion.
And I think you'd find even if we based morality on a strictly cost/benefit analysis behaving in a way that clearly brings harm to others is typically not going to bring you any long term benefit. Especially if other people are basing their own morality on a similar structure because their clear solution would be to eliminate you. Such arguments are at best short sighted.
Aside from that, we are in many ways beholden to our biology and humans are wired to be social animals and have all of the biological features that come with that. Just looking at the brain chemistry side of things we can see that when we act in socially positive ways our brains release oxytocin, serotonin, and dopamine which people tend to really enjoy. I suppose you could ask why would our bodies do this, wondering if perhaps this was something that must have been designed in. But there's a pretty easy evolutionary answer in that if the behaviors being encouraged improve the group's (not the individual's, by the way) chances of surviving to the next generation then those changes are going to persist.
