I don't think of evil as a purely intentional category, and I do think of it as bound up with stupidity which can turn even good will to unfortunate ends (as when one sneer's at one's political opponents as "well-intentioned"). People are seldom any less corrupt and wicked for wanting to be good, and are often very much the worse for wanting to think of themselves as good while they go about their habitual corruption and wickedness - the fairly widespread human habit of coming up with clever rationales for callous and idiotic behaviour. Here stupidity is augmented and abetted by a certain quickwittedness; but it's no less stupid for that. Perhaps the underlying category is "error". Neither evil nor stupidity can abide a commitment to truth (which is not the same as a claim to know truth). I have a gut-feeling that almost nothing I have heard so far, from anyone, about Afghanistan is adequately truthful: the realities that would speak for themselves (civilian death figures, for instance) are persistently occluded and will probably take a long time to emerge in full. Absent the proper materials of debate, there is no debate. All opinions stink.
