Not uncommonly in these kinds of accidents, they'll push it lower and lower on each subsequent approach, hoping the next one will work out. Finally, while well below mins they get off course or become spatially disoriented while looking for the runway. It's an easy and well documented trap that will catch pilots out if they allow themselves to cave into the temptation push it just a little lower.
I'm actually less concerned about doing repetitive approaches to mins because that's what I've always experienced in training and checking events. If you stay on course and don't go below mins during any segment of the approach, there's nothing in your path to hit. (theoretically anyway) The trouble usually appears during the transition from instrument to visual reference, especially when this takes place while near or below mins.
Discipline is the only remedy. Don't descend below mins unless you have the required references! The temptation to "cheat" has snatched many otherwise capable pilots right out of this life. In some wx circumstances, another approach may be fruitful. Such as when the visibility and/or ceiling are trending toward improvement. Two or perhaps even three attempts may be rational in some circumstances. But six? This one started reading like an accident report long before that.
