You haven't actually suggested any way in which the guy's work and behaviour could be viewed "three-dimensionally". While I can agree that discourse especially online slips into dehumanisation of (real or imagined) enemies too easily... this is really not a case where this is the incorrect approach.

Edit: Regarding the guy's family, I can agree that they did not deserve the death of the father/husband. But that does not really concern the guy by himself, his own moral character, it's someone else's problem. When a criminal gets sent to jail or executed, does anyone really give a crap about how much his family will suffer from that? Not really, the criminal is assumed to be a morally independent being that can tell right from wrong by himself, and his failure to do that is his own.
