Didn't Jean Vianney have a similar seminary experience (with his teachers) with the addition of uncharitable fellow seminarians.?  Also Father Damian if I remember correctly had it really rough in seminary.   Maybe some things never change.

More Christian charity needed in the seminaries, convents and even
Among the laity too.

And let's not forget good old St. Joseph Desa of Copertino, patron of struggling students.

There are of course two (or more) sides to every story.  It does seem that this particular seminarian had some issues.  So, for instance, his constant forceful emphasis about how he needed hours and hours of vigorous exercise per day suggest that he had certain issues that might not be compatible with the duties of state typically required of a priest or a religious.  I knew lots of guys who got up an hour earlier than everyone else and went for a long run.  If that isn't enough, then I think you've got some problems that are incompatible with the priesthood.  Doesn't by itself necessarily mean that there's anything wrong with you, but perhaps the priesthood isn't a fit then.

Now I saw a lot that I disagreed with in the formation process myself, but my attitude was that I am who I am to a certain extent.  If someone could persuade me that there was something wrong or incorrect about any particular attitude or opinion of mine, then that's cool.  But, at the end of the day, I thought for myself, and I didn't let the other swirl bother me much.  I just went about doing what I felt that I had to do.  Problems happen, however, when the priests continue to emphasize obedience and humility to the point that the seminarian thinks that he has to conform mentally and emotionally to be a clone of the particular Frenchman who happens to be running the seminary at any given time, or otherwise there's something wrong with him.  By trying to adopt an attitude of humility, they start to judge things about themselves to be wrong that just happen to be various personality traits or character attributes that are on their own morally indifferent.  That's when the psychological problems start.  "I know that this thing about me is defective and wrong, but I can't change it."  That's a FAR CRY from "Well, there's something about me that's not a fit for the priesthood."  Of course, the problem is that back in the normal times of the Church there were SO MANY ORDERS and different permutations on options and choices for religious orders and so many different WAYS of living out the priesthood or religious life that there was almost always SOMETHING that suited a person's temperament or personality traits.  Just because one doesn't, for instance, find resonance with Jesuit or Franciscan or Dominican or Cistercian or diocesan priest spirituality, it DOESN'T MEAN THAT ONE DOESN'T HAVE A VOCATION.

SSPX has LONG held the absurd view that if one doesn't fit into the SSPX seminary spirituality then one does NOT HAVE A VOCATION.  That's utterly ridiculous.  Not only that, but it also often narrowed even more, so that if you didn't have the spirituality of the FRENCH SSPX, then you didn't have a vocation, despite the fact that it could simply be that French CULTURE and the French MINDSET didn't resonate with you.

The superior of the monastery I was with briefly, was initially kind, welcoming and charitable. Then be brought in a suspect priest to help out with formation. We soon discovered how incompetent the superior was and how this was damaging the foundation of the fledgling community. A few years later he was arrested for child molestation, and defrocked. It took a while for to recover from this debacle.FRagging your superior office as they did in Nam does have an analagous parallel here.

This dynamic happens over and over again!!

 Experts say that 1 in 25 people is a sociopath.  The collateral damage is enormous, at its very worst in religious houses or schools --the military--wherever the system of order requires a holy type of obedience.  It takes years to sort out, but so many get cast to the wayside beforehand.  

Ladislaus, I am sure you know that nobody goes to a monastery to become a priest but to become a monk. The superior of the monastery decides who among the monks will become priests. Perhaps it is not like that anymore in the Novus Ordo monasteries.

There is truth in this, yet one may aspire to be a priest within a monastic order. But you do become a monk first, then we wait for what Holy Mother Church through Her priors and abbots perceive about one becoming a priest.

Imagine if all these political games of attrition were never played then the SSPX would much bigger and stronger.
