If I Was A Super-Hero

You lifted your hand at the guy and he started to float. He started freaking out and begging you to stop. You then swing your hand at the direction of the wall and he got swung to it. Now he is in real pain but you wouldn't stop. You swung he to the opposite wall and he hit it. You kept doing this until he became a bloody mess floating around. Now everybody is cowering at the corner. They saw what you did. Should you kill them?
