@Doomer i don't think it was 
planned, he is a normal person, he made 
decisions on spot, based on the 
situation, there was no time to 
think about anything, if you stop to think about his situation:
- He receive info that the adventurers and soldiers would attack him, them he decides to leave, he 
did not planned to fight people on the woods, his plan was to 
avoid confrontation and don't kill anyone, his plan failed and he 
reacted to the situation, killing people that tried to kill him, he did his best to spare the adventurers that attacked him, but showed no mercy for the soldier, that was 
during combat, it was a 
reaction, once combat ended, of course he would spare anyone that did not wanted to fight, on the first place he 
did not wanted to fight anyone.
- He receive a request to infiltrate the capital and rescue the emperor, the plan was 
sneak in, secure the target, and 
get out, the weapons he used were non lethal ones, dude used sleeping gas and paralysis needles, he 
did not wanted to kill anyone, now that he is running away, and people are being killed to serve as a distraction and he is 
on combat he is 
reacting again, he did not planned to kill people or spare people on combat, was 
not supposed to be any combat, he is just a normal person, reacting to the situation.
Pretty solid writing if you ask me.
