I would hazard a guess that the Jesuits are not particualry different than any other group of priests generally (there are always exceptions) in that they have had a goodly number of difficulties. It is difficult to say with any real authority how they are as most information is anecdotal. We have a Jesuit pastor and he is no slouch; he is orthodox and does a fine job as a pastor. I have met a couple of others I would not recommend to anyone. I have also known others who are fine priests.
As with any number of situations in the Church, things change. All things do not change at once, ever; the pendulum moves slower than we would wish. But move it does. The issues that a 50 or 60 year old Jesuit deals with are not the issues a 30 year old Jesuit is facing. The difficulty is that often, we only see the 50 and 60 year old ones, as they are the most prominent; and the presumption is that if they are that way, then all of them are.
It goes the same with seminaries; there are some which had few problems; some that still have major problems; those that are in transition, those that are dealing well with the problems, those that are not. We have a tendency to paint with broad brushes, often without realizing that we are doing so. Some of that is due to the fact that those who color the paint are very obvious and attract a lot of attention; those who do not color the paint are quiet, not in the spotlight, and not hearing from them, we presume they do not exist.
If the OP is interested in the Jesuits, he would do well to investigate as much as possible, and not take the first , second or even third comments as necessarily encapsulating all truth.
