Here's some information on the symbolism.
Animal Motif: Delsin sports a stylized two-headed raven logo on the back of his jacket and a Coast Salish raven tattoo on his left arm. And Your Reward Is Clothes: You unlock various jackets for Delsin by doing things like kicking the DUP out of the various districts in Seattle, completing all of the Cole's Legacy DLC missions and completing all the Paper Trail missions. Subverted by their leader who is actually the opposite. They also have blood purity tests that they use to separate the genetically different from the rest of society.
A Nazi by Any Other Name: The DUP have stormtroopers, a torturous concentration camp, and unlimited authority to bully, round up, and abuse citizens at their leisure. Bonus evil points for the same drug dealers also being involved in sex trafficking as the player is charged with freeing their "merchandise" at various points in the game. Played straight with the Drug Dealers who Delsin dismisses the deaths of as, "Only drug dealers." Possibly Justified as a Native American is likely to have a disproportionate likelihood of seeing the destructiveness of narcotics on communities and would want them removed by any means. Always Chaotic Evil: The DUP has this subverted as there's a number of members that are trying to do the right thing.
In the Evil Ending Delsin reveals he wants to do this to everyone held prisoner. For example, if he's using Neon powers and the player wants to use Smoke, you have to find smoke in the game to change Delsin's powers. However, he can only use one at once in gameplay and in story. All Your Powers Combined: Delsin is able to absorb and retain the powers of multiple other Conduits at once.However, playing through Paper Trail reveals that only 90% of conduits were killed. The Hero ending of the previous game made it seem like Cole sacrificed himself and the Conduits of the world in order to save the majority of the human population. An explanation for why Conduits are still a thing.The fact that Fetch's parents are apparently trying to track her down and reconcile with her.The existence of active groups of Conduit Rights activists.Some of the important details revealed include: All There in the Manual: The Paper Trail free DLC offers a lot of details on the setting and characters.InFAMOUS Second Son provides examples of: Due to the Wham Episode Grand Finale for Cole at the end of the previous game, expect spoilers galore for inFAMOUS and inFAMOUS 2.
