How would you feel if your weak little brother came to rescue you against your wishes?

Your little brother is like a flee against your super powered executioners. At first they didn't care about him. He was nothing to them but then during the battle, he revealed his hidden power unconsciously and it terrified everyone. Your executioners saw a glimpse into his future and realize how great of a threat to them he'll be. Now they want him dead. They can't allow him to live and become a threat to them.
