Many did leave, but many did not since they thought "this couldn't be happening to ME."

That's possible, but about 70% left, and plenty couldn't find a place to "leave" to. Personally, I've seen nothing to make me believe denial was a factor. And no, those who stayed didn't forsee that extermination was their ultimate fate. Germany was, after all, a civilized European nation.
