Are The Views and Writings of Carl Jung Immoral?

I went to a prayer meeting one night at a local Catholic Church in Bethal Park, PA. I was having a hard time sitting there because I hardly ever go to church anymore, let alone a prayer meeting. I was surprised and befuddled when I heard one lady refer to Carl Jung as being immoral. I had read some of Carl Jung when I was at a CCAC South Campus. It never occured to me that what he wrote would be perceived as immoral or moral, eitherway. That's why I'm putting this question before you.
