If you're unsure of Catholicism, but maybe want to learn more, I suggest reading anything Scott Hahn has written. A former Protestant turned Catholic who came to the conclusion of the Church holding the One True Faith through many years of intense research and soul-searching. Truly some great stuff to read, even if you don't end up joining the Church.

Or Taylor Marshall's book "Infiltration" about the plot to destroy the Church from within gives good insight into why the Church has so much corruption and disgusting people at the top. Similar to our own government and country, honestly. But just like America, I won't abandon the Church simply because of corruption. America, and the Catholic Church, are my home and I won't leave them to be taken over and destroyed by evil people.
