The problem with OMD wasn`t that Petere wasn`t taking responsibility - he was, in his own screwed up way. He believed that it was his choice to out himself during Civil War that was responsible for the shooting, and that by doing this he could fix the mistake. The problem with OMD was the logic and justification for the execution. `We are going to split up MJ and Peter. We know this is controversial, so we promise not to use magic to do it. We also understand Peter is supposed to be strongly moral and at least Christian in name, so they will not be getting a divorce. Instead he is going to make a deal with the Devil so that the Devil can use his powers to rewrite time instead. Oh, and to make sure this works we are going to show that every healer, scientist, and doctor we have on the roster is utterly incompetent.`
