some is true(wher did you get 90%? is that a fact?) but there are alot of good things contributed by religions. im not very religious but the fact that bad things are comming from a belief that is sopposed to be preaching good is very hypocritic. there is little difference from the world and how people behaved 2000 years ago and now. people were nasty, greedy, selfish, kind, loving, giving and it remains today.
