Many people often think of the famous phrase Voldemort said in Harry Potter and the Chamber of Secrets. "I AM LORD VOLDEMORT..."
If found it interesting how this name comes from Tom Marvolo Riddle. Voldemort was angry and ashamed that he was of half-blood wizardry, although he doesn't want to admit it. Many indeed thought that Voldemort was a pure-blood wizard. He fooled some Death Eaters in the process as well. What I find interesing about Voldemort's power is that it was unquestionable. Nobody could say an opinion that wouldn't resolve in Voldemort having their neck.
The interesting part really is, is that Voldemort was the true weak one. He separated his soul into seven, as said in the Half-Blood Prince. He was so thirsty for power, that he was willing to kill, and split his soul into seven. Once your soul is into that many pieces, you are hardly human anymore. That's why Voldemort hardly looked human. With slits for a nose, red beady eyes, bald, and skin as white as the pale moonlight.
Voldemort drank unicorn blood, giving him a half-life, a cursed life. Firenze told this to Harry in Harry Potter and the Sorcerer's Stone. Voldemort had nothing on his mind but power, and on the way, he lost every scanty part of humanity he had left. Dumbledore was wise not to let him have the Defense Against the Dark Arts position. Dumbledore was the only one who truly knew about Voldemort's past, and what brought him to be the killer he was presently. Voldemort was definitely a peculiar character.
