Do you have a desire to kill people?

Not at all. But the world we live in is pretty fucked up from that perspective. There are ex military contractor guys on youtube talking about their weapons and how they used a certain rifle to fight off invaders in the middle east. Nobody seems to care that the people on the other end of those bullets may have families.

My interest in this is purely philosophical. If you have a what is effectively a lawless country, where native populace has the desire to kill you, to what extent could you engage with that in a moral framework?
