As for anyone who has issues with Dion not taking further vengeance against his would-be killers, it does fit with his personality, to turn the other cheek. They beat him, tried to kill him, and now he is not only saving them once more with his healing, he will show he's stronger than they are in vanquishing this monster. His own need to give them the same injuries isn't needed when they are broken mentally, doomed to their pathetic wrath and how it consumed their lives. They are small, weak, and pathetic. Let them live in their misery, their weakness, and knowing the worst part is Dion could have destroyed them but didn't.
