Welcome Sheena!

I don't like too much the idea of the "heroic sacrifice that redeems the bad guy". As a start, I don't think of Sawyer as a bad guy, he's in the "gray zone" as almost every other character in this show, plus he has already proved that he's able of selfishless actions and has joined the A team every time there was the need (with the only exception of the Jack rescue). Accepting to die to save someone else's life? It's what he did in I Do. And the storyline of the final sacrifice is a bit of a clichè. I would enjoy a lot more to see his little steps to come to terms with what he has done and who he is, like in the past seasons (and hoping he's overcome the Cooper thing).
