However, it also means that you cant (without GM intervention) just say that the weapon 10 evocation you hit the group of mortal gangbangers with left them all miraculously alive. Thats not really within the realm of reason, considering that a weapon 4 attack is a grenade (which granted, people have survived), I cant really think of something that would constitute a weapon 10 attack.
My point is you can "be forced to kill" if survival is not within the realm of reason.
Otherwise I find your post to be very interesting.
Actually, if you are being "forced to kill" by the mechanics of the game, you can figure that an NPC with Average
Endurance has 3 boxes of Stress. Plus 2 for Mild Consequence, plus 4 for a Moderate Consequence, plus 6 for a Severe Consequence, plus 8 for the one (and only) Extreme Consequence means that you have to do a minimum of 23 Shifts of Damage in order to guarantee a
Taken Out result which you can assign the value of "Killed." This is established as a difficulty for magically Transforming a character (and it is pointed out that
death is a Transformation. So "accidentally" killing another character is not going to happen. However this is just my opinion (based on the mechanics in the book) and I could be wrong.
