This sounds like Revan to me. Revan holds the knowledge of betrayal, he/she had been betrayed in heart (by Malak) and will betray in turn (canonically speaking, he/she betrays in turn, by helping the Jedi and the Republic defeat the Sith).
It doesn't really apply to DS Revan, but with the believable, sense making 'civil war' concept, it does apply to LS Revan, who betrays his/her allies, the Republic and the Jedi by being a DS Sith Lord in the civil war idea.
