4 playthroughs wow.. I feel your pain..
I can't remember all of the names but here is what I've done to get this trophy.
-shop owner killed during the robbery
- all of the finger prints removed from the Manfred shop so you don't end up at the police station in the next chapter.
- Scott let drown his partner girl in the car.
- let Kramer die and don't give him his pills.
-Madison dies in the killer apartment
-Ethan don't get to the warehouse so he never see the killer
-Jeyden dies during the fight with origami killer in the last chapter.
That's what I've done to get this trophy and I did not had any problems with it on ps4 or ps3
All need to be done in one playthrough without chapter select,
Youbcan start from the chapter that you need to change the outcome and from there finish the game.
