In my novel, the protagonist is a normal guy whose mother was killed brutally by his kidnapper. He'll soon to desire revenge and maybe you could say he'll almost be the bad guy in the storyline. So, how should I start the novel? Should I start back when he was normal? Or when he started to take revenge from the world? Of course, if I begin with him taking revenge, I'll describe why he's doing so and also tell his memories through the novel. It's about pain and human struggle.
