Sorry, but BOB wasn't killing the children to save them. I understand why it came across to you that way, though. "Make an angel out of them" was actually a rewrite of a line I liked better, "Make them mine," as if he was a predator bringing down prey. However, in context it appeared to mean that he was molesting the children, and I didn't want the story to go in that direction. It was already upsetting enough. So, I softened the line while still keeping the meaning, that he was ending their lives.



So, why did BOB kill children? Even he doesn't know. He's aware that he's a sociopath, he knows what he's doing is evil, but he can't see clearly enough into his own mind to understand his own motivations. He just knows that there are times he's fine being "the schmuck in the Fredbear costume" and there were times when he had to hurt someone.



You're spot on with the Puppet. BOB wanted Ian out of his hair, as the kid might actually be a threat to him. He deliberately switched methods so that killing wouldn't be linked to the others.



I just realized that, of all the children he offed, the one he didn't try to "make an angel" of is the one who has come closest to becoming one.
