I wanna thank you for posting the cutscenes, both of them

Well it depends on what is your beliefs are, the people who are trying to save the ark believe that isolation is the best way to survive however the people who are trying to escape the ark believe that freedom is the best way to go. I believe both sides actually achieve their goals in story actually, the one side escapes the ark the other side saves the Ark by defending the reactor. So it depends on what you think is right I don't thing any side is bad here but If i would be on that are I would really want to escape it and if you watch the other sides ending they find life outside the ark actually.

Honestly, if anything, the resistance are the bad guys. The story is that the Earth was being destroyed by natural disasters, and the Ark, which was originally designed as an experimental, floating, self sufficient city, was the only place left in the world that was safe. So people started trying to find it and quite a few of them actually did end up finding it, and they were welcomed into the city. But the Ark was only designed to hold 5,000 people, and with all the refugees coming in, they were at 45,000 and increasing. The refugees started the rebellion because they didn't have enough food or shelter to live and they believed that the rest of the Ark was holding out on them, and the Ark had to develop a security force to counter the rebellion. Tldr: the rebels are refugees who came to the Ark and now want to destroy it because they don't think they're being treated fairly.

yep
