He has never killed an 'innocent' directly but there have been situation where I set up a Mexican standoff with vampires and the vampires were using a bunch of college students as shields, the vamps were like 'don't come any closer or we will kill them all' he said 'meh' and jumped the distance between them beheading the vamp in one stroke and got the students killed in the crossfire, when the others in the party asked if that was necessary he replied "very". Then there was the time he accepted a job from a fae no less to kill a rogue pixie, before taking the job he asked was the pixie evil to which the fae replied "you could say that" and his response was "good enough for me".
