Are you asking from the perspective of the person making mistakes? If so, then here's what I think:

If that person is willing to learn but is struggling with a fight, leaving doesn't make that person learn and that person will still need to struggle with the fight with another group. So if the party is willing to have that person, then that person should stay rather than simply jump from group to group that may have different ideas on how to do the fight.

If it's from the perspective of the party, then it's up to the party to communicate expectations. If it's a farm party and not a learning party, then there's no reason to put up with the struggling player, but they can simply communicate with that player and allow that person to be more self-aware and leave on their own instead of kicking them right away.
