"You'd be trying to end the world, right? End it in such a way that the people at large would suffer. In that case, I wouldn't hesitate to use weakness against you if it meant coming out victorious."

There isn't really a charming way to tell someone you'd exploit their weaknesses if they were your enemy, apparently!
