Both Nightingales and Dark Brotherhood don't steal or kill without guidance of higher beings. As a Nightingale you have Nocturnal by your side, whom you respect and grant your very soul when you die. She is your goddess in every sense.

As a DB, you get your orders from the Night Mother. In a way, Night Mother oversees all activities by DB. Besides giving strict activities (DB forever quests) every time everyone does the Black Sacrament. She was the one that literally saved your life from flames and massacre. She also requested to continue with your contract to kill the emperor. She's connected with the Sithis. Even when she's silent, she's there. Astrid tried to guide DB without this deity and we all know how that ended up. The order Keeper->Listener is as active as ever.
