You're aware that earth is billions of years old, right? With a population of 7.1 billion people on it. There are small towns with more history and more people to it. And just to make this relevant to what I said, Mutant kind had 1.72 million, that number dropped to 198. In one day. And we were still hunted, still hated. And the million that lost their powers were displaced, and in danger, because bigots wanted them dead too. Me and seven children were on the run, five of which had lost their mutation, when I was brought onto a train. After my shoulder had been blown out by a moly coated lapua round. Someone was sitting in a tree, waiting for me, or one of the kids, with a sniper rifle. So please don't belittle the difference between here and there.
Her strengths are her healing factor, and before you go and say 'well I can heal fast too' she can jump from a height that would normally squish someone like a bug, and stand and walk away in seconds. She's been shot thousands of times. Some in the head, some in the heart. She's faced down Scarlet Witch in one of her crazy person tirades and walked away with nothing more than a few old memories brought to the forefront of her mind. She has extensive knowledge in demolitions, weaponry and poisons. She is a black belt in more than 24 different styles of fighting hand to hand. She's got a mind for instant strategy. She prefers to do things on her own. So I'd say her weakness is in a team, and social behavior, outside of killing people. Her weakness was Logan. If there's anyway to kill her, he would have known.
The only way she's a danger to you, is if you make her a danger to you. If you and your family become a threat to this place, that is how she is a danger to you. You're talking like a person ready to start a fight for no reason. You become a threat to her family? You wont have time to plan. And you wont see her coming. So your best choice of action is to stop thinking about taking her on. Your mother died protecting you, do you think she would do any less for her children? She has been given direct orders not to do harm to anyone unless they become a threat to the safety and well being of the citizens of this place. Your best choice of action if you're really worried about her, is to find out how you pissed her off and undo it.
No, most mass murders are to busy thinking about their next kill.
