[quote="Kara"]I think demons by nature arent exactly self sacrificing. But thats just me.
However I was thinking back to when Angels were first mentioned. I wonder if the Angels that were mentioned back there in the Houses of the Holy (i think thats what that ep was called) will turn up in Season 5. But thats completely off topic.[/quote
I definitely agree that sacrificing themselves is not part of the demon nature but I believe that the big difference could be that Lucifer is somehow like a God for them.
The male Crossroad demon sacrificed himself because he believed in Lucifer ("I made piece with my Lord"). He only had to spill the secret to save his own skin but the sticked with the great demon plan!
I got the impression that Lucifer is like a God the demons whorship, so it could be that some demons are even willing to sacrifice themselves in order to free him, even if it means death for them!
BTW even Alistair mentions religion when he taunts Dean in 4.16. "Believe me son I wouldn't lie about that, it's a kind of religious sort of thing with me"
It would also explain why Ruby could be evil. Maybe even she is part of the big end game plan.
I'm curious how they will solve this riddle!
