Even it's condemnation of the player doesn't work because of the unreliable narrator and scripted events forcing the players hand. As the video says, the ending is meant to be a slide show of all the bad things you did, but the player has clean hands because all the bad stuff was either "Walker" doing those things, or twisted via the "Walker's crazy" excuse.
Edit: My point is that, as a game that you're meant to think about the themes and morals of FPS games, any serious analysis falls apart, at which point it's fanbase would accuse you of nit picking, not understanding it, or just FPS fans mad at being called out.
