McDuffie's reasoning, sadly, represents one of his flaws: instead of being something that even we could understand, he over explains it and creates an answer that's confusing and could've been done better. In short, my answer to "it doesn't matter", that I posted here on the forums, being because Owlman knew he was going to kill himself regardless, and decided not to save himself with the device that Batman threw at him before he took off, makes more sense and should've been the answer, instead of MuDuffie's...explantation that even I cannot explain myself. It's just unnecessary, and why something like mine which is simplier wasn't used, I don't know why.
