Osiris

"Don't you think that your brother dragged you back into that catastrophic mess because he’d rather damn you with him than be alone?"

- Osiris to Sam Winchester

Osiris is the Egyptian god of the afterlife, transition, death, life, the dead, resurrection, regeneration, fertility and ruler of the underworld; who put people who feel guilty on trial, and sentenced them to death. He commanded ghosts or specters to carry out the sentence.

Season 7
Osiris went to a local bar where he found people who felt guilty. He later grabbed Matthew Hammond, Christopher Fisher, and Warren and took them to his court where he held a trial and condemned them. Dean Winchester bumped into him in a bar, where Dean told his guilt to the bartender.

After Dean left the bar, Osiris took him to a farm where he put Dean on trial. Sam stepped in as his lawyer. Osiris called witnesses; Jo Harvelle, Sam and Dean himself. In the end, Dean was found guilty and Osiris told him that he would die soon. Just before Dean could be killed, Sam used a ram's horn and put Osiris into a centuries long sleep freeing Dean from death. Dean still felt guilty about the things in the past and for lying to his brother about Amy Pond.
