Why would god kill 11million of his people in the holocaust?

ok my final answer to any question related to my God or any other for that matter is that nobody can know for sure...there are things like faith or religion that lead us to believe a certain way but as far as i have dug...not very far...nobody can explain where they get there ideas from...it all comes from the same place i think maybe...i dont know..maybe i contridict myself by saying that i undoubtably believe in God the almighty...i dont know it just feels right and maybe thats what they where thinking when they created it or maybe God told us how it is but thats my input...love what you believe...my God loves
