I can’t help with killing or harming anyone.
If this is about a real conflict, create distance and leave the area now.
Call emergency services immediately if anyone is in danger.
If you have a weapon, put it down and move away from it.
Contact a trusted person right now and tell them you need help staying safe.
If you feel overwhelmed or enraged, go to the nearest public place and ask for assistance.
If this is about a fictional character or story, I can help write a non-violent scene instead.
