You are analyzing a fraction of his personality.
Sure, but a very important fraction
Look to his stimulus and subsequent response towards his genocide (of a vicious enemy).
Ah, but see, I don't know that an INFJ would "treat" themselves the way he does, by recreating his home and wife and happily going on with his life as though nothing had happened. Sure he goes into self-judgement when forced to reveal his crime, but it doesn't look like he would ever face it *voluntarily*, if left on his own. I personally couldn't live like that: I'd have to ATONE for my crime, one way or the other. I most definitely would NOT just go on with my life.
But then of course, all of this happens only three days after the attack. He's still under the shock of everything that happened, and he's looking for solace, thus the re-creating of his wife and home... (Which by the way smells very much of Si, a very *not* INFJ function...)
See, that's the problem with DomNis: we need TIME to absorb what happens. And time is exactly what we do NOT get in this case. We don't know how Kevin changes - or not - over the following months and years. If he just keeps on enjoying his private little life, then he's definitely no INFJ. If he faces up to what he did and seeks to somehow atone for his crime, then I can maybe see INFJ.
But then here's another thing: the way he stuck to his VALUES in the face of the danger his home and wife were confronted to. That's not INFJ, that's INFP. When confronted with an emotional situation (like being attacked by an alien race and threatened with total destruction), INFJs are far more likely to take a short-term approach: what is needed NOW? What do my family and community need from me? It's the INFPs who will choose the higher ground and stick to their values no matter what.
And it's the INFPs who are the most likely to throw open the gates of Hell, all values be damned, because you emotionally hurt them...
So I'll go for INFP, maybe
