World - Religion

This would be completely disagreed by almost 99% of the population of the world, but i would say religion has caused many more wars, and many more deaths. Me myself, i go to temple, i am jewish. I pray to god. Nothing happens. In the Torah, it says god gives us oppurtunities to do the things we wish for. I have not gotten one oppurtunity for what i wished for. Sadly. Sometimes things do happen which i wish for. So i feel like god sometimes is there.
Back to the thing where religion causes war. Well religion isn't the main specific reason that causes war. There are other things that happen that cause it. Religion takes a big part.
Examples:
War in iraq is caused because of the two different religions the Shiites and the other people i forget their names (sorry)
Adolph hitler, was rejected from a art school, the headmaster at the school was jewish. He was also believed to have gotten a disease from a jewish prostetute, which caused him to go crazy.
He probably wanted to get back on the jews... which he did but much worse... He was also "supposedly" going "crazy" which was actually a jews fault. This doesn't really point out how religion caused the war. It does point out how instead of getting back on those people, he thought of the persons religion and got back on the religion not the person. Even though it really was that one persons fault. I think if there was no religion involved he would go crazy, and maybe would have convinced germany to attack other nations. During the war though. They killed jews and attacked other nations. Without religion they would of only attacked other nations which is not as worse as when they killed the jews that lived in their country.
History would be completely different without religion, i am not exactly sure if it would be worse or better if there had been no religion. In my opinion though i would think it may be a little better.
