I would of put a poll, but i figured people would vote before reading the OP.
Lets think, in real life if this whole storyline was to go down, would you be Security, or Resistance, but don't choose so fast. I said realistically, so would you rather be on the Security living a bit cooshier lifestyle than the Resistance, but knowing deep in your heart you are only letting others live in poverty, but, if you were to break off from the security to help the resistance, you would have to sacrifice your families good life for a trash one, would you put your family through that? Or vice Versa, You are a resistance fighter, you have enough resources to live, but you want more, you also want to leave the ark, but you know that if you leave, you may doom your family, because there may actually be no mainland, and you and your family will starve, floating through the ocean. On the other hand, you also know that the security may only be doing what they do to protect their families, are you just going to kill them, is that fair?
Wrap your mind round that. Yeah.
ROAR!
First off a note: The game releases tommorrow. As such I have not played it and all I'm going off is a general sense of what the sides are fighting for through the realeased materials. The canon in game may drastically change this. Oh well.
Now that that's done, I think your specific interpretation of the Security is somewhat biased in favor of the Resistance's outlook on them. From the guests point of view, the Security are just hired guns operating to force the Founders' views and rulings onto all citizens of the Ark. From their perspective this makes some sense: they're living in poverty and it seems like they aren't getting their fair share of the resources. But it's important to remember that this game was specifically designed to have no "good guy/bad guy" dynamic. Both sides have legitimate reasons for fighting and both whole-heartedly think they're right.
Take into consideration that the Founders made and intially solely populated the Ark. It was their home, paid for and constructed to house them. The guests are in their view exactly like what their name implies: houseguests who happened by sheer luck to stumble onto this massive floating utopia out in the middle of nowhere. Frankly, the fact that the Founders allowed them to stay and live on their home is testament to their generosity: this is a place that swelled from 5000 to
ten times that before the game's setting. Naturally resources are stretched to their limit, with each and every new guest causing more problems in the overall sustainibilty of the island. Would the Founders want to try and solve this, perhaps by coming up with new ways to house this hugely inflated population in a sustainable manner? I'm inclined to say yes. Maybe there's a REASON the random refugees aren't getting as much food/water as the people who might have some know-how in how to fix the problem. Despite what they say, they arent entirely starving. If they want to start trying to help, why not move towards inventing some solution ideas themselves instead of firebombing Security squads and stealing supply reserves? Food for thought.
Anyways, like I said, both sides were intricately designed to come of as legitimate "good guys." The only reason I went into detail regarding the Security's reasons was because I think of the two they're the easiest to misinterpret as just being powerhungry or typical "I hate you darn terrorists" cops. What would I be in real life? No idea, guess it depends on if I was born on the ark or came across it on a makeshift raft...
