Religious beliefs don’t make people do bad things. They don’t make people do good things either.
Beliefs generally don’t make people do anything at all. That is, beliefs are not really *causal* to behavior. People tend to act like the people around them, the people they associate with and can observe (in person or virtually). We adopt beliefs primarily as ex post facto justifications for *why* we acted the way we did. They make it possible for us to live with our actions, but they don’t *cause* our actions.
Culture? Ideology? Religion? Not particularly useful indicators of how someone will behave.
