Killing them would also have made his future difficult:
[ul]
[li] is unarmed while the three are dead
[li] is supposedly a rank F
[li] is a new citizen of the town
[li] is unknown by pretty much everyone
[/ul]
All this would make any authority believe it was premeditated murder, or to be more precise, assassination, even with a hint of being from an enemy nation.
Criminal charges for that would be : death by the axe.
