Many pretend to believe and are hypocrites.

The Catholic Answers

Very few would pretend to believe in hell. An immense number pretend to themselves that they do not believe, and they do so in order to carry on as tranquilly as possible in evil conduct. Those who want to suppress hell are not characterized by a real desire to defend the honor of God, to be more scrupulous in the observance of His laws, and to be more faithful in the fulfillment of their duties.
