Read the "Stark Disassembled" arc (or whatever the title is exactly). Tony Stark paid a very high price there for his mistakes. Or at least he would have if he didn't return shortly after. But he is not necessarily the same guy. In a way, Tony Stark died there in Afghanistan and was replaced with a younger version of himself (pre-extremis).
