Cain

"Abel wasn't talking to God. He was talking to Lucifer. Lucifer was gonna make my brother into his pet, I couldn't bear to watch him be corrupted, so I offered a deal — Abel's soul in Heaven for my soul in Hell. Lucifer accepted... as long as I was the one who sent Abel to Heaven. So, I killed him. Became a soldier of Hell — a knight."

- Cain To His Descendant Dean Winchester

Cain is the brother of Abel and a retired demon known as the Father of Murder who used to train the Knights of Hell. He and his brother are also the direct ancestors to Sam and Dean.

Human Life
Cain was the firstborn son of Adam and Eve, the first human born, and the older brother of Abel. Although it was originally and commonly thought that Cain was jealous of his brother Abel, and killed him out of rage and contempt, Cain later revealed that Abel was in fact talking to Lucifer, not God as formerly thought. In an effort to protect his brother from corruption, Cain offered Lucifer a deal. Cain offered himself to Lucifer so that Abel would go to Heaven instead. Lucifer agreed, on the condition that Cain himself would send his brother to Heaven. Thus, Abel was struck down by Cain using the First Blade, which he created from the jawbone of an animal.

After this, Lucifer branded Cain's right arm with the Mark of Cain, binding him to the First Blade.

Life as a Demon
After killing his brother, Cain descended into Hell and became a high-ranking demon soldier. He was considered to be the most terrible demon to ever walk the Earth before suddenly vanishing. This act of killing between brothers would set the precedent of their descendants being the vessels of Michael and Lucifer, and thus, again require a brother killing a brother during the Apocalypse.



Cain was the founder and mentor of the Knights of Hell. He created the entire order with his bare hands, and also killed all but one with the First Blade.

In 1863 in Jasper Springs, Mississippi, Abaddon, the last remaining Knight, possessed Cain's wife Colette, in an attempt to coerce Cain to return to his work as the leader of the Knights. When Cain declined, Abaddon killed Colette. It was during then Cain made a promise to a dying Colette that he would retire from his work as a Knight.

During Cain's disappearance, all other demons thought or hoped he was dead. Crowley described him to be "the best at being the worst."

21st Century
Cain lived his life alone, and was a bee collector in Missouri. He met Dean and Crowley when they came looking for the first blade to kill Abaddon. Cain was initially unwilling and sent them away, warning them to never return. However, still searching for the blade, they broke back into his home, and were caught when Cain returned. Meanwhile, a veritable horde of demons arrived. Interested by Dean, Cain tested him to see if he could live up to his reputation. Cain realized that the hunter was similar to himself. Going back to his wife's grave, just as the demons forces were advancing Cain decided to transfer the Mark of Cain to Dean who accepted his offer. He then teleported Dean and Crowley to safety after making Dean promise to return and kill him after killing Abaddon. He then took on an entire army of demons single-handedly and massacred them.

Personality
Unlike most demons, Cain still possessed a good deal of his humanity and was one of the few demons to show love. He dearly loved his brother Abel, willingly becoming Lucifer's soldier to save Abel, and personally murdering him so that Abel would get into Heaven. He spent thousands of years doing terrible and brutal things with the knights. However he fell in love with a woman named Colette, who loved him even after she found what he was. This apparently restored most of Cain's humanity. Following his love dying because of Abaddon, Cain gave up his life of violence in a promise to her, and buried his head declaring himself retired.

By the time Dean came to him looking for the First Blade, Cain was living an isolated life like a normal man and showed a passion for bees. Initially seeming apathetic and uncaring towards Dean, Cain refused to help, but once Dean proved his strength, Cain agreed to return partially to old ways. However, he was tired of life and what he was going to do, he asked Dean to kill him once Abaddon was dead, showing a death wish.

Cain also had an interest in Dean Winchester, having despite being retired heard a lot about him. He considered Dean and him to be very alike and was impressed to see Dean lived up to his reputation. He eventually agreed he was worthy of taking the Mark of Cain, making him the one to kill Cain.

Cain also showed an affinity for bees, taking up beekeeping after retiring, he considered them noble creatures.

Powers and Abilities
As one of the oldest to appear and the first Knight of Hell, Cain is an extremely powerful demon. His reputation alone made Crowley reluctant to go anywhere near him, opting that he and Dean go "a world away" from Cain as possible. He could kill other demons with a mere touch. He could even prevent Crowley, the King of Hell and a powerful demon himself, from escaping and speaking just by a simple gesture. His strength was also shown when he killed an army of demons single-handedly.

 * Demonic Possession - He possesses humans to exist on Earth. He had been in the same vessel for over a hundred years.

 * Telekinesis - He could move objects by snapping his fingers.
 * Teleportation - He teleported from across a field to beside Dean and Crowley and then to Collette's grave and back.

Trivia

 * Cain is the first and only demon to display the ability to smite.
 * Cain is one of the few demons to possess a vessel for an extended period of time: He's been possessing his current vessel for over a hundred years.
 * Cain is similar to Dean in many ways. Both of them wanted to keep their younger brothers from being corrupted. They also took extreme measures to make sure their brothers were saved, regardless of the rest of the consequences. Cain also remarked that Dean's bravery was very much like his. They both had gone to hell for a deal they made to protect their brothers. Finally, they both carried the same bloodline that could host the archangels.
 * Cain showed a considerable amount more humanity than any other demon, this is possible because he made the agreement to become a demon out of love towards his brother. It could also be because Collette loved him unconditionally.
 * As the result of Abaddon's death, Cain is the only knight of hell to be alive.
