Lame finish if you ask me.
Ofc it shows alot of interesting stories to come, but the whole ending was like... ummm w/e.
Die trying to complete trial 1 - 2, find out trial 3 = death, and change your mind about the whole thing

Yes, but that wasn't because of Sam. When Dean told him he would die finnishing the trails he responded with "So, what!?".
So actually, it was Dean who convinced that he couldn't do this without Sam, that he needed him. That they would "Find Another way, because they Always do".
