There is a hell of a lot of religious people out there that through the centuries have killed, tortorted and oppressed a large number of people.

So by your defintion the Ayatollahs in Iran who run a theocracy, (a fancy word for religious dictatorship) are not religious because they do bad things? Oppress women's rights, lock up political/religous prisoners, execute non-believers, execute apostates, execute those non-muslims that have sex with muslim women etc.
