however you're engaging in huge confirmation bias here:

No the sample is just too wide for it to be a coincidence. There is certainly something bad to religion that causes people to behave this way, while I have not observed the same behavior with other groups.

I live in a pretty secular town, so the number of Christians here is not even that high, if anything I am inflating the proportionality here.

But it is exactly that, the fact that the general population behaves relatively normally, while the religious group which is like 30-40% does not. That is a pattern that shouldn't be ignored.

The thought that just occurred to me is that Christianity doesn't cause evil behavior, but it does give people a way to clear their conscience for evil behavior.

Exactly, for once I agree with you here.

Every single mobster that I have read about in the newspapers or in TV had been deeply religious. Now is that a coincidence too? Or they have a deep cognitive bias and are struggling to justify their immoral behavior through religion.
