But it’s the sort of thing that traditional game theory would advise if killing was legal.
I don’t get it… He wouldn’t gain anything by killing you (ETA: other than what your father/wife/whoever would gain by killing him after he kills you), so why would you be afraid he would do that? (Also, I’m not sure the assumptions of traditional game theory apply to humans.)
This really is a case where imposing an external incentive can stop people from mutually defecting at every turn.
If this was the case, I would expect places with less harsh penalties, or with lower probabilities of being convicted, to have a significantly higher homicide rate (all other things being equal). Does anyone have statistics about that? (Though all other things are seldom equal… Maybe the short/medium term effects of a change in legislation within a given country would be better data.)

Have you seen The Dark Knight? This is exactly the situation with the two boats. (Not going into spoiler-y detail.) Causal decision theory demands that you kill the other person as quickly and safely (to you) as possible, just as it demands that you always defect on the one-shot (or known-iteration) Prisoner’s Dilemma.
Anyway, I think you shouldn’t end up murdering each other even in that case, and if everyone were timeless decision theorists (and this was mutual knowledge) they wouldn’t. But among humans? Plenty of them would.

I haven’t read it yet, but I think this is basically the thesis of Steven Pinker’s The Better Angels of our Nature.
