The Martha thing is totally bizarre for multiple reasons. Obviously, "getting shot = bad mother" is insane troll logic of the highest order. But even beyond that, the woman raised Batman. A person that remarkable does not spring into existence in a vacuum, and as cool as Alfred is, Bruce can't be laid entirely at his door either. I mean, if you're saying that the idea of Batman is a bad thing, that Bruce is a playacting moron and a net negative for the universe in which he lives, okay, sure, that's an indictment of Martha, but I'm skeptical that "both Bruce and the DCU would be better off if Batman had never existed" is supposed to be part of the premise.
