A “Licence to Meddle” isn’t exactly a “Licence to Kill”…but it’ll do in a pinch.
She now has Carte Blanche to go ahead and preemptively kill /every/ major threat that Yori would face from now on, so long as she does it /before/ Yori knows about it or before it actually becomes a threat. I love it.
Eliminating a known threat, even if it is only known to Matrix and the other outsider, could still be considered saving the life of Yori or his friends: if I know that a man is planning to kill you but you have no idea and I go ahead and kill him, I have saved your life even if you never find out. So, no, I don’t think this is a carte blanche for preemtive strikes. Yori and crew will still have to do the fighting and killing themselves, Matrix can just make sure they have the equipment, medical aid, and maybe even the information they need to get the job done.
Medical aid- which she already seemed ready to provide if it would have indeed been needed- is literally saving someones life, ‘tho. So she ain’t even hesitating to break those rules, if the situation calls for it…….
