Sam being focussed on his goals is Sam being an adult. I'm not so sure he'd see it as looking after his own self-interest. I don't see a lot of benefit to Sam in the path he's chosen.
From the moral perspective...I don't know. Kriple & Co are so focussed on their beloved Mary-Sue, Dean, we've been given very little insight into what Sam's goal actually is. If he's purely motivated by revenge, which he's implied on the few occasions he's been allowed to talk about it, then yeah, there's a moral issue there. But I'd like to think his vengeance, like John's, is a means to an end: kill Lilith and the worst of the bad stuff goes away. My impression from the flashbacks we got was that Sam knows he's going down a bad road and has decided that the end justifies the means, even if the means is to sacrifice himself: it's no different, really, from the deal Dean made for him. (Except it is, because Dean's motives were selfish and Sam has at least half an eye on the big picture.)
So far, I'm firmly on Sam's "side". He's right about Dean: Dean is weak, and he is holding Sam back from his goal. And Dean has failed to make a convincing case for why Sam should stop. "Because God says so" is not a case, it's nonsense. Dean could make that case, if he chose he could make Sam understand. But he's too busy being all emo about Hell to freaking try.
...I guess you caught me on a bad day. Sorry for the rant :-)
