Well, considering that I am Agnostic, I meet many people with a different belief system than mine. I don't care as long as they aren't beating me about the head with their chosen book and god until I succumb. You will find many who are religious who do think everyone who doesn't think like they do is wrong and destined to eternal damnation. There are several who've already answered your question, and I'm sure more to come. Many, many wars have been fought in the name of religion, so yes, there are many who think they are the only correct way and will even kill.

Jews don't believe in Hell though. Not sure about Muslims.
