Well, this may be unofficial Church teaching, but I have personal experience in this matter. It’s a great question the OP ask so don’t take it lightly. See the question as a blessing.
Here is my experience. When I first joined I started a thread of my awareness of hell, and that people go to it. Again, part of my process as a Catholic was now twelve years ago to give up all my old friends and all my bad habits and up my Christianity. But it was only until last year did I finally come to terms that there was a hell and people go to it. Again, a big part of me clung to childish beliefs of universal salvation. So, in realizing there was a Hell, for months I grieved for the sinner. Then to a certain extent, although I cannot know whether I am saved, I felt survivors guilt. Right now my life is a blessing because of the changes I made twelve years ago. But, I can’t spread this message to nonbelievers all I can do is pray for them.
So, in seeing that passage, right now, it is very profound and truthful. I can’t be like a rebellious angel and reject God because people will go to.Hell. Again, like the wealthy man who couldn’t give up his possessions to follow Jesus, there is a certain portion of us who can’t let go of the sinner to follow Jesus. Does that make sense?
Well, now in my journey towards God, I know God is just and merciful willing to forgive all ignorance. I know those who knock sincerely will get an answer. I know, like Fatima, I must pray for the discernment and repentance of as many people out there. But in the end I must love God and let go of the sinner, no matter how much I want them to find God and be saved. Again, part of this process is to better appreciate all Christian denominations and everyone on the Christian path, even if I may not agree with all their viewpoints.
Again, a big part of me had to acknowledge because of the media and all the clickbait, I was ignorant in not appreciating my Christian brothers in Faith. Now I don’t let politics divide me. I’m just grateful they are Christian. But in the end when it comes to the sinner who openly rejects God a reviles in sin, no matter how bad I feel for them I must let them go.
