Maybe it's because I'm an older sibling. But I've always found Dean's story harder to take, more heart breaking. He's the character that I relate to, the one I always want to be okay and the one who can help me if I'm ever down. I adore him, and his mental health issues (cause there are some) and his drinking, his violent nature should 100% be focussed on more. His constant protective nature is something that I am in awe of and also completely understand. He has given up so so much of himself and let go of many opportunities to save so many people and it breaks my heart. His mother has never been a mother, his father is more like a commanding officer than a parent and Sam does seem to be John's favourite, Sam got protected and Dean got punished for wanting a little space. Dean had to look after Sam constantly and when he didn't he was told he failed, and that has stuck with him through his whole life. Deny it all you want but in season 8 Sam abandoned Dean and the people he left behind (Kevin), he didn't try to save him, didn't look for him and kept a promise that was made to be broken, I was not a fan of that storyline, because although Sam would sacrifice himself, you saw that when he got freedom, he put himslef first, when Sammy went to hell dean would try anything, he would still try to hunt and still try to keep an ear out for anything supernatural. Dean is the strongest and best character is this show for me because of his sacrifices and his never ending loyalty to his family (not just Sammy but Jodie, Cas etc) He is flawed and doesn't always do the right thing for the right reason but that makes him human and that makes him better than a lot of other TV show characters because you see what someone who has no options would do to save the people he loves. I adore Sammy but again i have this connection with dean that is what makes the show special, along with the sibling bond and J2.
Who are 7 what do I want from this life inside this kind of darkness of immortal messengers of one's true calling of a similar spirit to know only the voice from within a atonement of reason and breathe breaking the silence of matrimony revised to give of everlasting to go beyond furthermore
