Like I said, you use that as an example of something bad Law-wise, and how is it different from just overpowering someone with magic, preventing them from fleeing, running, getting a successful attack off, etc, and then killing them? If anything, that's more protracted and emotionally intense.
I don't see any way to have a consistent and sensible standard where putting an enemy to sleep and then killing them conventionally earns you Lawbreaker, and using multiple magics to stop the enemy and then killing them conventionally doesn't.
I believe I mentioned it 'may not earn', in the context that it implied I believed it didn't; however it in the end, its down to individual GM's. I'm sorry, but I'm not quite sure which part of my comment you're disagreeing with.
Doing something WITH MAGIC. Putting someone to sleep isn't killing them with magic, unless falling asleep causes them to crash their car and die or the like.
Magic is who you are. Magic is your intent put into existence. Both of these concepts are stated in the books &/or RPG at one point or another. If you are the type of person to kill, no matter how you pretty it up or go about it, you're likely the type of person that'd cross the lines of magic. Which is best reflected as an aspect, not the lawbreaker power. Until you directly break the laws as you say.
But then, I believe my original point was too that effect.
When you're used to seeing the worst things that humanity/wizards can do, it's hard for you to see any good in anyone. If you don't see a stain, they're just concealing it real well.
Except for your fellow Wardens, the men and women who back you up when you're sent out against a warlock. Those are the only people you can trust.
And Harry was trained by the worst sort of rogue...of course he's guilty of something.
Morgan has at least one aspects related to how he views the Laws and other magic users. A Warden could easily have the aspect, "Jaded & Blackened from all the murder", etc as someone suggested earlier.
Aspects are how this should be handled, in
my opinion. It doesn't take a house rule, aspects are already supposed to be used to reflect your character in such ways.
