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. Devils think that life itself is one momentous struggle. Angels know that there is no real contentment to be found outside of that light which is their nature. Devils find fulfillment in their endlessly haunting wants which is their nature. Devils lash out.
