Believe me, I know how much this means to you, but this isn't the way to do it. I don't think the curse will work on it's own and we need to figure out a plan before we just go at him. And no one should be doing it alone.
I won't cut you out. You can be involved, Merlin knows we were at your age, but you can't just charge at him and hope it will work. Your parents wouldn't have wanted it, Harry and your grandmother and no one here would want it. Help us figure it out, help keep others safe. You're no good to the fight if you're dead.
