hii are there any instances where you can prove dean raised sam?

thejabberwock:

Well, you can check out the entirety of my parental unit dean tag. which is all about the unfair burden dean was forced to take on, filling in the parental role when John was absent, sometimes for weeks at a time: 

There are many more examples in that tag. If you mean did Dean take care of Sam all by himself, then the answer is no because John was there too (and so was Bobby and apparently, pastor Jim) when he wasn’t off hunting for weeks at a time but even then Dean seems to have taken on more of a partner role to John than a child role

But I think all the proof you really need is here when the show finally put it into words:

So, yes, there is definitive proof that Dean filled the role of both mother and father to Sam, which means he helped raise him.
