Definetly Hagrid.

Hagrid'd give his life for you. Dumbledore'd save you both. :)

Hagrid

Hagrid would never betray you, not on purpose at least. He has the heart in the right place :)
But I think Dumbledore is loyal too.

Hagrid : 100%
Dumbledore : 0%

dumbledore is a tiny bit loyal,he just like saves your life maybe and wise :/
But i cant spot a bit in the book/film were hes like loyal,he is to harry abit (cos hes the boy who lived lol) but a lil grim.

Hagrid for sure. If you see how Dumbledore acts in Harry Potter and the Goblet of Fire, who would you think is more loyal?

Totally

Because of this (and a decent amount of other evidence), I think Hagrid was a Hufflepuff.

^I thought JKR had confirmed somewhere that he was a Gryffindor. I could imagine the Hat considering Hufflepuff as well though.

^Yeah, I read that afterwards. I wish he had been a Hufflepuff, though. He'd never be sorted into Slytherin and he doesn't at all strike me as a Ravenclaw, either.
