How to get the Saintly Achievement/Trophy

To get the Saintly achievement/trophy you must complete the game without killing anybody. This means you will not be able to use your gun and will have to rely on your baton to take out enemies. If for whatever reason you do accidentally kill someone you will need to reload the checkpoint. You also need to make sure you avoid choosing to kill anyone during the dialogue choices between the levels.
