A religion doesn't determine the nature and actions of a person.
Everyone can be a moral monster!
I can't agree with you on this. Sometimes, a religion determines the nature and actions of a person. When some brainwashed fellow shouts "Allah Akbar" does a suicide bombing, don't you think that the religion doesn't have any impact on their actions?
No, religion doesn't impact on it, actually suicide is a sin according to religion, and killing other people is also a sin. There is nothing in common with religion itself, they just use religion to provoke hatred, though actually brainwash people by other means like threatening to theit families etc.
