The Mark of Cain was one half of the weapon Cain used against the Knights of Hell. It was the source of the power of the First Blade. Cain later transferred it to Dean, who Cain thought of as someone similar to him, so that the hunter could kill Abaddon.
When Dean used the First Blade for the first time, he felt a murderous rage that did not dissipate after he killed a victim with it.
Notes
- This mark was given to Cain by Lucifer. There are only two possible scenarios in which Cain could receive this mark; either Lucifer touched him using a vessel or in his true form, somehow.
- The mark of Cain can only be worn by someone worthy, as explained by Cain. The conditions required to be considered such are unknown although Cain stated that Dean is very similar to him as both brothers sacrificed themselves in order to save Sam and Abel respectively. Dean inquired as to whether he needed to be a killer like Cain, to which he replied he did: It's possible that the mark can only be worn by people who have killed, as well as other requirements.
