I'm probably in the minority here but I really don't want Jesse to die. I mean, he's wrong for snitching on Walt and working with the DEA, for sure. But at the same time, think about what triggered it. The final straw was the discovery that Walt had been lying to him about Brock, and that Walt poisoned him. Walt involving kids in his schemes is reminiscent of Gus, and Jesse has a soft spot for kids. Whether it was that Tomas kid that killed Combo or those junkie's redhead kid or the kid Todd shot, or Brock. Dude likes kids and there isn't anything wrong with that. So I kinda get him, like Walt has been playing him this whole time, and while I feel that they both cared about each other at one point, I don't think there's any going back to that now that Hank is dead, arguably because of Jesse. Sure, he was a no-good junkie himself at one point, but his growth as a person is comparable to Walt's transformation to Heisenberg. If anything, at the beginning, Walt was good and Jesse was bad, now Jesse is good and Walt is bad (if you wanna think of it as black and white). I'm a big fan of Walt and I'm rolling with Team Heisenberg. I want dude to get his money back, avenge Hank by killing the Aryans, and I want his original goal of making sure his family will be fine after he's gone to be accomplished (don't know how that's possible now though, especially with Walt Jr.'s attitude towards the whole situation).
And like I said, I will be sincerely sad if Jesse dies. Dude was a drug addict and came up by cookin meth, found a girl he cared about and got her back into drugs, she ODed because of it, Walt let her die, then dude finds another girl only to find out she used to use too, cares about her and her kid, only to find out that Walt poisoned the kid and let him think that it was his fault for a while, and then watches her get shot in the head on her porch. Now, he's enslaved by some psychopath to keep cooking - the thing that started his entire series of events. How can you guys not feel bad for him?
Sidenote: what was the significance of the two black birds Jesse looks up at before he was about to be shot by the Aryans? And has anyone else noticed that there are times (in the last few episodes) that Walt is wearing the watch that Jesse gave him?
