Liroj killed one human and a few elves in the past. With the elves, he was drugged and doesn't really remembers, but he did regret the human. I haven't brought it up recently, but it probably still bothers him enough to want to spare his friend this sort of feelings.
man, these elves make goblins look cuddly!
But they wear bunny fur suits, how can they not be cuddly???
Yeah, these elves are BAD. Great looking sequence!
A lot of things are BAD in that world.
Cynics would say it's like reality, but no, it has a whole other lot of scary things!
