Hitler was Catholic. 

But yes. It's safe to say religion doesn't determine your morality. Your morality determines your morality. 

The important thing to remember is to remain skeptical at all times. If you're not skeptical you're up for grabs. Faith or no faith, we should all be skeptics and not agree with something just because a Christian, atheist, conservative, or liberal said it. 

Remember the golden rule and treat others as you'd wish to be treated and we'll all end up okay. If you start treating others how someone in your group says they should be treated you might fall short or slip into arrogance.
