I don't really want to call him a villain even though he's actually a really rather nasty piece of work. In my novel the baddie is after my main character because he needs to use her for a certain purpose which I can't reveal for fear of giving away all my secrets! But it's the core point of the whole plot, throughout the book you're led to believe it's for one reason and then (hopefully) the truth is a surprise at the end. Anyway, I digress, the book is a vampire novel (see plot creation for details) but it's not romanticising vampires. There is a royal family in the vampire world, really it's to do with the oldest vampire family who were created by the first vampire. The first vampire only created two new vampires, the Draconis line and the Corvus line. Draconis, being first, has always been in power although Corvus has always resented this. The 'baddie' is a Corvus and was friends with the 'Draconis' heir before a woman came between them and Draconis befriended a vampire hunter and created a treaty with humans, outlining new laws, etc. Corvus is very much of the idea that vampires are supreme and had his friend killed. Although he's sounding like a pretty nasty piece of work we need to keep in mind that this man is a father and married a woman he didn't really love just to keep his own parents happy, the woman he loved was taken by his friend, and he feels like his friend betrayed him by valuing humans as much as he does his own people. Do you think this character would work better if I portray him in a way which would make the main character and the readers sympathise with him for his situation or is it better in young adult books to have a villain who is just evil without knowing the motives for his actions or personality?
