Sam Is The Abomination

I wonder if Sam isn't the key to finding Purgatory. Just think about it. He is like some abomination because before he jumped into Hell, he was a human being possessed by an angel and he had a ton of demon blood in him too. How is that even possible? Plus there was Sam's soul in there too. Maybe Crowley right now is using Dean to help find Purgatory because he doesn't really have Sam's soul and is looking for it himself. Maybe by Sam getting his soul back, he'll remember where Purgatory is.
I love the fans who think Dean is the one who knows where Purgatory is. Dean has never been called an abomination, he's never been considered a monster or a freak. Also, he's never had powers. He's never been possessed by an angel or a demon, like Sam has. And he's never drank demon blood.
Who knows where Sam's soul really went when he was stabbed by Jake? Maybe he went to Purgatory and maybe that's where all the other psychic children's souls went to. I've been thinking about all this for days at work for something to do.
Here's something about Crowley. He used Sam and Dean before and he's probably using Dean now. Maybe he was using Grampa Campbell to find Sam's soul and it wasn't working and now he's using Dean to. Crowley is a demon and he lies all the time or do people forget that. Like he's telling the truth about holding Sam's soul, when he might be trying to get it back to find Purgatory. Nothing is ever as it seems. Maybe Sam getting his soul back, would not be a good thing. Just like killing Lilith and how many other things that the Winchester's have done. Crowley and all the other demons have used Sam and Dean constantly and that's probably what's going on now.
This is just a theory I have and it's probably wrong like all the rest, but I do think there is more to everything and Crowley is up to more than he's saying. Crowley thinks Sam and Dean are morons and he's probably proving that they are right now because they believe what he's saying or Dean does. It seems that Dean always believes what how many demons and angels are saying and never questions some of their crap because he thinks they're telling him the truth, but they're lying to Sam. It's actually kind of funny.

Another thing about Sam. Sam was considered the special child. So what made Sam special. What is it about him that he can be Lucifer's vessel? He can drink demon blood and have powers. I hope we learn more about why Sam was considered special and what it is about him. It seems that even Sam without his soul has something like powers or strength. I hope we get some explanation or more about Sam soon.
