Like the title says: How do I justify a Dark Brotherhood Dovahkiin? The only time I beat the mq was with an Imperial supporting, Talos worshiping, champion of the people Nord. I've played as a Morag Tong Nerevarine in Morrowind, but the MT are an honorable bunch. Whereas the DB are a bunch of delusional psychopathic killers.

So my question is this: How do I make a delusional Sithis worshiping psycho killer into the champion of Akatosh? In this playthrough I am not joining the Legion for obvious reasons nor the Stormcloaks,
