Anyone noticed how in the first inFAMOUS if you choose the evil ending you can't change your karma to good no matter how much you do (the black tar thing in front of your karma meter stops it), however if you choose to destroy the ray sphere (good ending) you can still turn evil. To me this is actually very dark, just think about what the game is saying here. Good men can always be corrupted and once corrupted can never go back. Wow that's dark. Whether you think the message is true or not doesn't matter, the fact that it merly suggests this is really dark and powerful - another reason why the first inFAMOUS is so great.
