This Trophy will obviously be obtained during your Good Karma play-through. As you play through the game do everything Good. Complete every Good side mission, make every Good Karma choice presented, heal all downed pedestrians you find, capture all downed enemies and you will eventually max out your Good Karma. If you make a few Evil choices you are still OK, there are a lot of ways to get Good Karma. However, avoid all of the Evil side missions and Karma choices and you should have no problems with this Trophy.
