I wasn't saying that it was a good thing that this happened, or minimizing the fact that people who shouldn't have been harmed were- just that observations along the lines of "this was evil and wrong and there's nothing else to say or think about this!" are invariably simplistic and useless.

Why should we ever reduce our response to such events to trite condemnation for the sake of trite condemnation?

Two things can be true at the same time: in this case, that the loss of the other people was an unspeakable tragedy, on the one hand, and that Mountbatten may have brought his fate on himself, and contributed through his actions to what happened to the others. So this isn't something that fits into smug, tidy little categories.
