For every hero, there should be a coward somewhere. Their perspective generally is going to be to save their own skin so what are they prepared to do to achieve that? Would they betray others to a dragon or other monster on the grounds it lets them off (and given these creatures are unlikely to keep their word how does the coward react when he/she/it realises they are still endangered?). What happens when someone else discovers the betrayal?
In my stories, a common complaint from my witches is that the fairytales are written from only one perspective - that of the fairies - so no wonder the witches get a bad press. My first published story, A Helping Hand in Bridge House Publishing's Alternative Renditions, looks at the Cinderella story from the angle of the younger ugly sister. Could you come up with stories that would be better if you took a character and their perspective different from the one you may originally have intended to use? Equally could you write a follow up story looking at events from the perspective of the villain. There could be some interesting material here.
