Literally, you wouldn't be responsible for the actions of a DE who got out of your bodybind. He understands that he got off light, and chooses to go back into the fray.

I hope this doesn't sound too snarky, but I can't resist because the image is cracking me. This makes the Battle of Hogwarts sound like Paintball. If you get hit by a bodybind, then you should--by the rules of etiquette--retire yourself and sit on the sidelines for the rest of the day.
