Angels have no fear of any dark place. Devils tremble in the Light and the dark. Angels are rewarded by their acts of self-sacrifice. Devils are punished by their intention to be selfish. Angels would rather die than fight over nothing.
Devils have no life outside of fighting which they do over everything and for any reason.
Angels never gossip. Devils like to light themselves on fire and then pull other devils into their flames so that they can dance in the searing heat with them. Angels attract Angels. Devils attract devils. Angels never struggle with the moment of life.
