Bellatrix had never been sensitive or queasy. The sight of blood had never disturbed her. Even at a young age, she already displayed sadistic tendencies. The pain of others thrilled her. The sounds of tortured screams aroused her. She lived in the darkness, and she loved every moment of it.
The Dark Lord only increased Bellatrix's desire for violence. Their relationship, however, was not that of equals. The Dark Lord was the master, and Bellatrix was the slave. But Bellatrix never saw herself as being a slave. The Dark Lord encouraged her to torture and to kill, and that was all that mattered to Bellatrix. She would do anything for the man, no the god, who required her to be nothing but cruel. That was who Bellatrix was, and that was exactly what the Dark Lord wanted.
Darkness meant strength and power. Most were too weak to embrace it. But not Bellatrix. Never Bellatrix. She and the Dark Lord would do great things together. The world was theirs for the taking.
Bellatrix didn't care who got hurt because of her twisted desires. Pleasing her lord and master was all that mattered to her. The strength and the power that her lord and master gave her was all that mattered to her.
The Dark Lord drew Bellatrix further and further into the darkness, and she gladly allowed him to lead the way. There was no place where he could possibly go that she would not eagerly and loyally follow.
There were many that would say that Bellatrix had always been evil, but she became more evil under the influence of the Dark Lord. Those people would also say that Bellatrix would not have done half of the things that she had done if she had not been doing it for her lord and master. He was the only one who gave her life true purpose and meaning. There was nothing that she wouldn't do for him.
There were many that considered a Bellatrix a monster for serving the Dark Lord with such passionate devotion. But Bellatrix could care less what people thought of her. All that mattered to her was how the Dark Lord thought of her. The Dark Lord's approval was everything to her.
The Dark Lord was Bellatrix's world. When he fell the first time, Bellatrix was completely devastated. She was willing to endure Azkaban without him because she could never imagine living a life of joy that did not include him. So, she gladly suffered for him.
When the Dark Lord returned, Bellatrix was beyond overjoyed. The part of her that had been missing was back. She was now once again complete.
It was perhaps for the best that Bellatrix died before her lord and master did. The sight of his body probably would have completely broken her.
Bellatrix had always loved the darkness. It came to no one's surprise, therefore, that she would only be capable of loving someone who loved the darkness just as much as she did.
