I don't understand what the point of Nere was. He's got such a time-sacred quest just for keeping him alive, and the only purpose of saving him seems to be immediately killing him after you rescue him. He doesn't end up doing anything for the player. What's the point in building him up like that?
To give you the illusion of free will, it's just like how voting works IRL, no matter what, you're screwed with the same option, while making you think that you had a choice between the 2 options given to you.
