Humans will engage in wars and genocides against other people just because they are other groups of humans. It doesn't matter what sort of thought process or ideology is used to justify it. But sure, look up things such as "the Armenian Question". Religious genocides existed before the Shoah. Heck, read some of the bible to see some more examples. Human sacrifice also has a long, long tradition in various religions. While the toll for any particular human sacrifice will be few in number, iterated over centuries it adds up.
