Biggs and Wander Spoiler!!!
This is what I got at the end and I'm suprised that I did did not see anyone mentioning this. In the end it felt like everything that Ludlow did was useless because he was still stuck in a corrupted system, but this time he went from being the pet of Wander to being the pet of a much more higher official who may be just as corrupted as Wander if not worst. Its like he is trap and any good cop would not want to continue in this type of environment. Just the fact that we have those in the higher up cheating and getting involve of in all sort of stuff prove that the buck does not stop with killing Wander. I saw the ending as sort of a gloomy one. Although Ludlow doesn't go to jail and is now being protected by the higher ups, if he continues to follow his conscious and should one day find out about other corrupt things going on in the higher up that would make Wander's sins seem like childplay's; if Ludlow should follow his conscious like he did with Wander he will not win this time because there will not any higher officials who will have his back like he did with Biggs who represented those in higher power.
Anyone felt like that too?
