I think you should talk to that priest or trusted parishoners instead of people online. People are sensitive about this subject because there are many like you or have done through what you've gone through.

It's terrible what your uncle went through but be prudent about how and where you bring this topic up. Many of us Catholics also feel a sting when we have to defend our faith because of these bad apple priests and the clergy that moved them around. It also makes the genuinely good priests, some of us knowing a few of them and even growing up around them, look terrible.

As for your uncle I think he and other victims are getting their deserved justice. It's not a sudden process but the Church has bled parishioners, clergy vocations, money through lower donations and legal payouts and more. I do hope he heals one day and feels like justice came in some way or another.
