Good-Bad Cat

You are Milton, a bipolar cat who after dying was taken to both Heaven and Hell where it shall remain for nine eternities.

Good Cat doesn't want to spend the rest of his eternity in Hell, so he kills as many demons as he can, so that he may be sent to Live in Heaven.

Bad Cat doesn't want to spend the rest of his eternity in Heaven, so he kills as many angels as he can, so that he may be sent to Burn in Hell.
