Why do you seem to believe He closed those gates after freeing the righteous dead, and that people are still going there rather that directly to the presence of God as the Bible itself teaches?
Because there were two gates; one to Hell [which are still closed and will never be breached) and one to the Limbo of the Fathers. which is now Purgatory.
You didn’t answer the question: Do you believe in a Hell were souls are eternally damned?
Besides that, the Apostle’s Creed says that Jesus descended into Hell, not descended into Purgatory anyways.
