So, murdering a murderer is murder ? ...

[dogtag]

I'd be more inclined to call it justice.
Assuming of course that the one he killed was the right one.

It's only "murder" because he did it without being officially ordered to search and destroy. Otherwise he did what he was trained to do in a war zone. I think this may be more about his handling of the corpse?
Unless hiding/burning the body was to create a simple disappearance in the eyes of the enemy. Sometimes certain bodies shouldn't be found for good reason.
