I don't like the idea of a morality based entirely on intention, but it does seem a little strange (or maybe not, given Card's mini-adult view of children) that there's no point at which Ender, or anyone else, gets presented as less morally culpable because children aren't expected to have informed intention. We don't try children as adults in the justice system even if they're supergeniuses, right? Sometimes the adults in the novel seem to be drifting towards that, but mostly they consider Ender innocent because they drove him to genocide and murder and/or they shielded him from the consequences. I haven't read Speaker for the Dead yet, but I don't much like the idea that Ender starts judging morality entirely in terms of intention - the reason he comes across as sympathetic against a morally dubious background is because he does consider himself a murderer in regard to the two boys he killed, even though he wasn't actively trying to kill them.

I like the discussion of bullying in the article, too. There does seem to be a lot of SF that strikes a particular chord with people who were once bright and socially awkward kids (and I'd say that as one of them), and there's something very seductive about the kind of stories that tell you the reason you're unhappy is because the world doesn't understand you and you're better than everyone else. It's the only reason I can think of for why 'Harrison Bergeron' is so popular, at any rate.
