So I've been down a rabbit hole but Tyrion is a million percent gonna be a bad guy by the end of the books at least.
Not only does Ghost attack him shen he goes to Winterfell the first time, but the rest of the Wolves do the same when he comes back after going to the Wall.
Like, that's about a wrap on it. The direwolves simply don't make mistakes. His arc is gonna be Tywin reborn.
And then, I read an old 1999 George interview after ACOK came out and he said, without any context needed "he (Tyrion) is a villain. And we all love good villains."
Throw in everything else in the books (Quaithe specficially listing him as a person not to be trusted, him raping the slave girl in ADWD), I just don't see how it all can be ignored? But PARTICULARLY the direwolves. Thatd a big, big, BIG tell.
