it sounds to me that you are afraid your friend might be hurting someone else and you have to watch them do it. whether it be physically or verbally. he keeps attacking you because even though he may not accually tell him to help him, watching him hurt someone gives you stress because you want to help the person but keep your friend. when your friend is handcuffed to the polar bear, your afraid your friend might be the next person that the evil friend hurts.
