Good question! Specifically the way it works is that if you pull a player out who is projected to have a detrimental outcome, he will take a hit to morale and also incur all of the penalties as if he had completed the program with a poor result.
There's also a very small window you have to decide if you pull a guy out, which is only when you receive a midterm report on his progress.
So it's more about cutting your losses than avoiding detrimental outcomes.
It's more like "your guy is really swinging and missing a lot now, do you want to leave him in there to figure it out or just give up on him and make room for someone else"
