10/1/2012: It doesn’t matter what the creature dealt damage to. If the creature dealt damage to another creature or a planeswalker, it doesn’t matter whether that creature or planeswalker is still on the battlefield.
10/1/2012: Avenging Arrow doesn’t affect the damage the creature dealt. It isn’t retroactively prevented.
