CMV: In Elder Scrolls V Skyrim, the Dragonborn should opt to murder Parthunaax

*What is better? To be born good or to overcome your evil nature through great effort?*

I know this is an unpopular opinion - I love our favourite grandaddy Dragon as much as anyone else. He is kind, wise and was instrumental to humanity throwing off the tyranny of the dragons. So please change my view people! 

But here is why he must die:

1) The dragonborn must side with the blades. Dragons raid villages and cities, slaughtering many people in their droves. The people live in terror of a dragon attack and many people are terrified to travel from one city to the next. Meanwhile the Grey beards, safe and protected, spend their day sitting on their ass talking at the sky. At the very least the blades are locating dragons and taking the fight to the dragons but they need the dragonborns help. For the greater good, one elderly dragon should be sacrificed. 



2) Parthunaax killed, tortured and enslaved many humans. He was also very high up the command chain (a top general I believe). His actions were akin to war crimes against humanity and he was so high up the command chain he cannot just claim he was following orders. The same way many Nazis were hunted down after WW2 and executed, Parthunaax should as well. 



3) Humans generally speaking by nature mostly crave freedom, company and security. Dragons are different. The same way we want to feel safe and free they want to rule over others and be venerated. It is *not in their nature to be good* and every day Parthunaax is fighting against that urge to massacre and enslave humans the same way an addict might always crave that next drink. You are the last known Dragonborn, actually able to properly kill a dragon, how can you leave the fate of humanity up to the mood of someone who is always in danger of relapse. 

Note as well dragons are Immortal creatures! So the risk isn't just for a few years or even a century. 



4) Following on from my last point. He literally betrayed Alduin when he was his right hand man - how can you be sure he would never betray humanity?

The dragonborn at the end of Skyrim is the effective head of dragonkind. The reason that, upon your return from sovngarde, there are many dragons on the throat of the world is because they were waiting to see who would be king.

As the effective leader of the majority of dragons, those under you are effectively agents of your will. To command effectively, you need a chain of command, and Parthunaax is the perfect candidate for second - especially since he's the only dragon who essentially followed your will of his own accord in the first place. Pragmatically, this is the best bet for the taming of dragonkind, and short that, or a genocide, Parthunaax is invaluable.
