In the Muslim world (which included parts of New Jersey), there were people who had parties over 9-11; if someone feels happy about killing civilians, there is something wrong with that person as a human being. That person is about the same level as the average serial killer.
All in all, I think my original instinct at 19 was the right one: Nukes should have been involved. First, ask for bin Laden, then nuke until either the Taliban personally hand him over, or Afghanistan was a sea of glass. Between twenty years of warfare and the disaster over the coming years, “Operation: Sea of Glass” might have killed fewer people in the long run.
