Well up till blonksy came along as abomination he was pretty much single minded, then failed to accept responsibility for his part in creating him (sheeping down to banner's questioning) and then wants to now help the hulk and let's him escape at the end but then ends up drunk in a bar without any real sense of achievement or purpose.
there was nothing particularly redeemable about the way he went about things with banner, his daughter or the hulk, let alone blonksy or anyone he had hurt by not making himself responsible. It's all even for a project that is no longer being funded (by my accounts).
So unless you saw he brought anything more to the table than that, i'm not particularly sure.
so yeah, he was an ass all the way through. One even willing to deviate from his hulk personal vendetta to help tony
