duplicity info
Castiel is an Angel of the Lord.
Before befriending Dean Winchester, he was loyal to Heaven, but after Dean convinced him to rebel in order to save humanity, he becomes a free agent. In this time, he attempts to fix Heaven's corruption, but his attempt causes terrible destruction and loss of life. His guilt feeds his already self-critical nature and becomes a festering self-hatred that only grows over the years as his attempts at penance fail again and again.
Now, he's hit a breaking point. After being confirmed "expendable" by the current villain, he allows Lucifer to be freed so that he can possess his vessel, believing Lucifer can better address the threat. When Dean tries to save him, he passively refuses the help, seemingly having lost all desire to live his own life.
