Afghanistan was in ruins long before 9/11, economically and morally. The US will no doubt pump billions into that country to give those folks a better life. Give people a helping hand and you'd think they'd be grateful, right?
However, why the hell is it our responsibility? The routing of the Taliban was not to liberate Afghanistan but to eliminate a threat that had demostrated the desire and will to attack us.
We don't have to make them love us to prevent them from attacking us. We could bomb them into oblivion and justly so. Fortunately for them, we aren't like "them".
