Imagine for a moment Cain were still alive. Imagine an antagonist who had been cursed by God to live endlessly as a fugitive and a vagabond until the end of time. Envision a villain who had spent countless lifetimes being shunned by all of humanity as punishment for having robbed his brother, Abel, of his time on Earth. It is unlikely one could even fathom the level of psychosis and paranoid delusional depravity such a creature would envelop. In “Destroyer of Souls; My Brother’s Keeper,” Van Oaks must track down and confront Cain, who has kidnapped Van’s younger brother, a genetics research scientist.
