Who Is Paarthunax?

A dragon nested at the throat of the world in Skyrim, Tamriel. He is the leader of the Gray Beards who has always trained the next dragon born

What's the moral dillema?

The blades who you meet realtively early on eventually at the end of the game want you to kill Paarthunax one of the last dragons as in their eyes all dragons are bad. However Paarthunax as overcome his dragon ways and lives at the summit of the world in peace.

Which choice is more "right"?

Most players when found with this choice choose not to kill Paarthunax even tho there is no option to reject the mission so they forever let the mission sit in their missions tab. Many players do this because of how nice Paarthunax truly is and as you play the game you get to know him more and he is beyond helpful throughout the game. All while the blades are beyond useless in the game and they bug you throughout the game with their missions of moral justice all while doing nothing.
