Richelle E. Goodrich said this quote

People love super heroes.  It's true we're  impressed by their bravery and fortitude, their supernatural gifts and physical brawn.  But the fact is, villains possess these same qualities.  So why our admiration for the hero and not the nemesis?  Because of virtue.   A super hero gives everything to defend what's good and right without seeking praise or reward.  Think about it.  All the great heroes give without taking, help without grumbling, sacrifice without asking recompense.  A super hero's real strength, what we absolutely fall in love with, is his finer virtue.
