I like being Paragon to both CloneShep and Maya.
CloneShep gives up, it is tragic. I consider him more damaged than irredeemably insane, but plot put him in that position on the ledge.
Maya hesitates in her antagonism. It is encouraging. In custody, I can imagine her having few qualms with providing strategic intelligence against Cerberus before I go on the final assault to the HQ.
I'm fine with there being two. I'm fine with there being many. No, he's not our Commander Shepard, but I don't think he's irredeemably evil, but like pretty much all of CAT6, I think he's been screwed with in the head enough that he'd need a mix of positive social ethical reinforcement and a purpose to fight the Reapers, not effing Commander Shepard.
I didn't hate CAT6, and the dialogue can support this - you can believe Shepard is just super annoyed at what CAT6 is doing to your ship and life, but you don't need to hate CAT6 themselves.
I'm not so absolutely attached to the Normandy that stealing it means an automatic death sentence no matter the other context and opportunities, and I'm not so absolutely attached to Commander Shepard that an attempt to take his identity means an automatic death sentence either. Typically it might, but I was okay with trying to procure assets for the war, not just destroying every single enemy in my way.
This doesn't mean I like CloneShep or Maya BTW. It means I can see their usefulness, and in a different plot, their possible redemption. ME3 was not that plot, but it gave us personal character choice and expression anyway.
