Antagonists in literature are lethal to varying degrees. In my opinion, the following antagonists are the most cunning and dangerous of the books I’ve read.
1. Voldemort (Tom Riddle) from Harry Potter by J.K. Rowling: Voldemort killed many innocent people and took pleasure in causing people pain. He was incapable of loving another person. In addition to all the atrocities Voldemort bestowed on others, he mutilated his own soul so that he would be nearly “invincible.” Like Mr. Curtain, he also used people for his own sinister purposes.
2. Valentine Morgenstern from The Mortal Instruments by Cassandra Clare: Valentine Morgenstern experienced on other people and even ruined some to the point of no repair. He also was in a way, a hypocrite, and persecuted anyone who disagreed or stood in his way.
3. Big Brother from Nineteen-Eighty Four by George Orwell: Big Brother had the Thought Police who monitored civilian’s thoughts for any signs of rebellion. He also sowed used brutal methods within the Ministry of Love, who dealt with something far from love.
4. President Snow or President Coin from the Hunger Games Trilogy by Suzanne Collins: Both presidents were ambitious and more than willing to kill those who stood in the way of their goal. While President Coin killed less than President Snow, she was responsible for Prim’s death by sending her into a dangerous area and then sending bombs into the same area.
5. Mr. Curtain from The Mysterious Benedict Society Trilogy by Trenton Lee Stewart: Mr. Curtain cultivated an obsession with mind control and control in general. He wiped memories of innocent people whose minds were never his and used slaves (the Helpers.) He also did not care for any people, but rather gave the appearance of caring in order to use people for his own purposes.
