Shout and hope people will hear you!
Try to think, and get a good solution. To survive.
Kill Person A, as quick as possible and get the Weapon. Without killing your friends. And walk away without saying anything to your friends.
Take it and kill one of your friends. Some friends will hate you, but some don't. Because you have the weapon.
Try to brainwash him and get the Magical Weapon.
Leave and don't kill your friends or even take the Weapon.
You are an Element expert in Electric Powers. You kill him with that power, and take the Weapons. But also kill one of your friends.

Use your friends to stop it.
A normal life again, with love.
A normal job, without troublesome things.
A Partner, and a job.

A Huge sword, and your voice!
