I don't know what really is happening.. may be it's cos Mark of cain which states that the bearer will lose all familial love so may be sam is doing so cos of that mark..
I seriously dunno what's with Sam.. is he being practical in that living a horrible life is way worse then death so.. yeah saving him was wrong.. and in doing so changing nature's path ?? out right rude? or just plain tired on living life under all the love dean gave and frustration that he never got the chance to return it??
I have no idea.. rifts between brothers have been the norm of this show season after season.. But this particular rift is turning into a chasm .. deep one at that in a fast pace..
May be this what lucifer intended when he said however the details change in "the end"
all I can see is that all these fresh level of guilt Kevin's death, Sam's apparent loss of brotherly relation and trust on Dean... will all turn the guilt thing so hard that Dean Might as well become another Cain full of dark cos even Carbon Under severe pressure turn to the hardest material on earth Diamond.. so may be the utter weight of guilt dean has now on his heart might turn him into a full blown monster ,, whome I am afraid sam has to kill .. which by the present scenario he will do gladly..
I have been tested earlier many times this season actually.. But if the weather continues to be so..and If the break up is imminent and is not clean with adequate explanation... or if making up is imminent and that is not done neatly...I might have to question my loyalty of 8 years which I put into it.. and have given more than the show demanded in everyway...for real!! and this time around IF they let down not the fan's wishes but Fan's sensibilities..
This show will be my top priority show till comes to it' natural end..yet...If things are not explained properly ...I might actually wean away from this show.. a daunting task...but not really impossible..
Sometimes Loyalty Have to bow down to Common sense .. specially when the task of balancing it is becoming tougher as it ages!!
