well i donno thats all stuff of the 20st century, religion was the cause of the crusades, and all of the wars through the middle ages, and the dark ages. look even in the 20th century. the hollocaste was caused by a difference in religion. SO many of the problems with the arab nations involve religious problems and difference in opinions on different traditions. well this may seem a little harsh but hope of an afterlife has also lead to many many more deaths in war, look at suicide bomber. look at crusaders so many of who went to war int he middle east cause they had commited sins and still wanted to go to heaven.

and as for your first point, it is irrelevent, i agree with you, thats what i was getting at, cause faith is not determined by proof of one thing or another. either you have faith or you dont.
