Okay, so here's my dilemma: My villain is a widowed king who has become a recluse since the passing of his wife. He was never mentally stable to begin with, but I need help with ideas on what makes him snap completely and want to kill off all the other kings and become supreme ruler. Please help this could make or break my story. And also the Hero of the story is the evil king's son. Since his mother was assassinated he has earned himself the nickname 'The Rogue Prince' from his people, since he is rarely at his father's palace and prefers to travel the countryside from kingdom to kingdom. I don't have a complete plot yet, it's still forming, but I know that during a rare visit to his father, he discovers the plot and confronts his dad. After a brief clash with the palace guards he escapes. After which his father begins putting wanted posters out offering a price for him dead or alive. If you need anymore information, just ask and I will do my best to help make it clear. Like I said the plot is still in the process of forming and any help I could get sorting out this bump in the road would be appreciated. The villain problem has been solved. Thank you to everyone who posted their ideas.
