Yeah. The story is on rails. It's not an RPG where you can choose the good path or the evil path. I can imagine feeling bad about playing the evil path in a game where you had the option not to do it. But, if you want to see the story in a linear game like that you have click the mouse in the way required to get to the next save point. Feeling superior about not finishing a game like that is like feeling superior because you read a book where the main character is an antihero, and you chose not to finish the book. Besides, it's "deep" for a modern AAA shooter video game, but not particularly deep or upsetting in terms of storytelling.
