When I played Peace Walker, I felt bad for him originally. "Wow, this guy is handicapped, seems like an ok guy, and his son is going to cheat on his second wife, and he is going to kill himself" was in the back of my mind for a lot of that game.
Now? Lol, yeah Huey can go fuck himself. If the one idea I can give Kojima credit with this games story is the fact the only reason Huey is able to walk in this game was to contrast that where as almost everyone from MSF lost something, he was the only one to gain.
The change of Huey into the most evil person on earth, in this game felt super abrupt and weird.
