Red has stated that there arnt necessarily divergent paths in the game but just a few choices get altered.
In chapter 4, when you meet the kid that shot you, you will get 2 choices. What those choices are is changed depending on if you have mostly good or mostly bad Karma.
Good Karma: 1. Forgive him. 2. Break his arm.
Bad Karma: 1. Break his arm. 2. Kill him.
in Chapter 5, when you are alone with Violet you have two choices.
Choice 1. Play a game with her --> Leads to voluntary and enthusiastic BJ.
Choice 2. Just get Drunk --> Leads to Violet passing out, allowing you to rape her in her sleep, then as she wakes up, finding out what you did, she threatens to go to the cops, you blackmail her to stay quiet and let herself continue to be raped in the future.
I haven't tested it on both save paths but I am going to ASSUME choice 2 doesn't show up if you've got all good Karma. I could be wrong tho!
