Initially filled with rage, and psychotic anger, he soon has a change of heart and regrets his mass murders after watching Mr. Hankey in, the "Grinchy-Poo Who Stole Christmas". Realizing what he did was wrong, he changes his tattoo from a swastika to a smiley-face and attempts to protect the boys from the gun-happy police.
