With enough imagination, M&J could be redeemed at anyone's eyes, but there is no way whatsoever of redeeming'em in everyone's eyes.
DPC wrote a movie, but made a game; the core problem isn't writing, it's the mechanics. A movie asks you to empathize with the protagonist's feelings, a game asks you to feel the protagonist's feelings.
Unless you felt exactly what DPC had in mind at every turn of the game, it didn't work for you; unless you feel exactly what he lays out in a future redemption arc, it won't work for you and, if it does, it won't work for somebody else.
