Evil Morty

[Potential Spoilers for Rick & Morty especially S01E10]

I'm all for the theory that the Morty we know isn't Rick's original grandson. Rick got his original grandson killed and travelled to another dimension where the Rick there is dead. I'm also for the theory that evil Morty with the eyepatch is aforementioned dead grandson who isn't actually dead and sought out revenge against his Rick (the Rick C-137 we know) for abandoning him.
