It might well be safer all around to help Barbas to curb Vile's power. But what if someone else comes along, decides to help Barbas, and claims the rueful axe? Clavicus Vile gains all his power back, but none of the restraint of Barbas.
You keep Clavicus and Barbas separated, rendering him nearly powerless. You can argue that not helping Barbas at all and ingoring the quest is the best option. Azura's relic is completely neutral, and in fact defying a Daedra's will results in a more dangerous and evil artifact.Ĭalvicus Vile. Meridia is downright benevolent, Sheogorath is kinda doing a good deed, Sanguine doesn't cause much harm unless you the character decide to be a dick to everyone, and even then it's mostly inconveniences. Not all of the Daedric quests are completely evil in their outcome.
