One man has the power to change the world for better or worse. It only takes one with the ruthlessness to back it up, and people will follow him. Doors will open for him. He can murder a quarter of the world. Consumed by rage and a desire to take power, he can make weapons of mass destruction. He can outline a manifesto and follow it to the letter. Evil has many forms, and Cain's murderous intent continues to seep into individuals, causing death wherever it goes, and this death comes in many forms. The children of Cain orchestrate bombings and school shootings. They cause pestilence, addiction, consumption, and sin. And this evil came from one man. This man severed the vein that issued a river of blood. The blood has never stopped. It's a blood that speaks; It has a voice. What is the voice saying to you? In The Man Who Murdered a Quarter of the World's Population, author Ira J-Ira offers an intriguing look at religion, family, and relationships. Using a raw approach to history and the Bible, he presents unique insight into one of the oldest stories of creation.
