Now I know what you're thinking. They are an embodiment of a certain aspect of mortal lives. This is true, but you take it far to literally. They do embody aspects of reality, but they do not perpetuate those aspects. Domination would exists whether Molag Bal exists or not. Each Aedra and each Daedra is capable of expanding upon the realms they embody. Azura is no less capable of being a dominating [censored] than Molag Bal. Boeitha is no less capable of destruction and change than Mehrunes Dagon.
Now that I have my interpretation out of the way. Its about time we killed one of these horrible beings. They have been defeated in the past. They are not invincible and they are not infallible. Three mere Chimer, powerful as they were not only went against the will of three of the Daedra, especially Azura, but one of those Chimer single handed defeated Mehrunes Dagon. Although said Chimer had some power of a god. So it is possible to defeat them!
Now its about time we found a way to finally kill a Daedric Prince. Now we know that the opposite is true. Daedra, and even Aedra can be created. Malacath and Sheogorath are examples for Daedric princes who were created. Arkay and Talos are examples of Aedra who were created. Now if they can be made, they can be unmade. I would argue that even Lorkhan now that his heart is destroyed is no longer in existence, but we are unsure of his total fate. Each Daedra is also their realm, realms can burn and be unmade.
Jyggalag or Hermas Mora are likely the only two princes to have this knowledge if it is not common knowledge. Since they had to imprison Jyggalag it is unlikely that killing a Daedric prince is common knowledge. Although much time has passed and many artifacts created. Hermas Mora may have some idea of what it would take, and Jyggalag would have calculated the possibility even if it was a low chance.
It is about time we shook up Tamriel and Tamriel lore. For thousands of years, the mortal races were subject to the whims of these so called gods. Its about time we fought back, like the Argorians of the Oblivion Crisis.
