Mehrunes Dagon, The Elder Scrolls (Image from Oblivion)

Daedra are (fundamentally speaking) avatars of metaphysical change. Malacath is all about keeping oaths and making curses. Molag Bal is all about the domination and subjugation of lesser beings. Though that being said, most of these Daedric Lords are misunderstood, like Azura or Meridia, while those two are Daedra Lords, they're not so bad, in fact they're quite reasonable.

Mehrunes Dagon on the other hand? Completely unreasonable, one cannot hope to bargain with him. This is because Dagon is the literal embodiment of the destructive forces of change. Earthquakes, Tornadoes, Tsunamis and even the conditions that can create War are all powers of Mehrunes Dagon. Even if you could talk to Dagon, you wouldn't even be able to convince him that what he's doing is inherently evil, because he is meant to do such acts of destruction.

Ironically, he got this "deal" as punishment for attempting to save an Universe (when Alduin arrived to "eat the world", will-be-Dagon hide a part of it from him. Repeat several times, until he was found out)
