Defense of others is a valid defense to a charge of a and b. So you must be sure what is going on and that could be tough to do. This is in a fistfight. It makes a difference if the guy on the bottom is unarmed and the guy on top is stabbing him. Then for him it may be the choice of complying with your commands or contracting a case of instantaneous lead poisoning, and you would be justified.
