Yeah, thats kinda were the "you control what your attacks do" thing kinda falls apart... With that kinda power... But anyway, to the current subject... I honestly don't know if the whole putting someone to sleep, or incapacitating them then killing them would break first law or not.. In all honesty, its very similar to the whole, you use a gust of wind, and knock someone off a building.. In fact, they have an even better chance to survive that then you after you knock them out..
The whole point of the matter... Is they are practically the same thing.. You knock someone off the building, its not you or the magic that kills them.. Its the fall.. But it was your intent to put them in a lethal situation, where they were completely helpless to protect themselves, as they fall to their deaths..
Its just the thought of this, and their similarity that puts me into such bind on the subject...
Consider this.
If you knock someone off a roof with magic, you killed them with magic. Your gust of wind is what propels them off the roof. It means you made the decision when making the wind to kill.
If you knock someone out with magic and then kill them, it is a BLADE that is killing them. Not your magic. The only decision you make when you knock them out is to knock them out.
To some that may seem like a fine line, but it's actually a pretty big difference.
By this line of reasoning, as a GM I would say that if a wizard kills a vampire in an apartment building with magic but the building burns down and kills a few families, whether or not the wizard was thinking about the other people in the building at the time would make the difference on whether they got the law breaker stunt or not.
I will say this again - the laws are not about morality. At all. You could be a really terrible, murdering wizard and not break any laws of magic.
I think some of the confusion here is that a few people are getting the laws mistaken for morality.
The laws exist to keep mortal magic users from turning into monsters - pretty much forces of nature for chaos and destruction. They are not there to keep people from killing each other.
