Has the leadership of the Catholic church almost completely gone over to Satan?
Since the Catholic Church was founded by Jesus: no.
However, please don't expect priests, friars, brothers, monks and nuns to be perfect and sinless. They are the same sinners that we all are.
They have just dedicated their entire adult lives to the work of Jesus: missionaries, orphanages, farming, baptisms, holy communions, confirmations, ordinations, hospitals, hospices, schools, churches, homes for unwed mothers, homes for the dying and so on.
It's a massive world-wide organization for human care, founded by Jesus.
I don't know of any other Christian, non-Catholic faith that has that kind of dedication and their own of clergy. Do you?
AND, you do know that if some Protestant minister does something bad it doesn't become world-wide news...because NO ONE CARES. Those who would want to "do their own thing" and resent the "straight and narrow" that we are urged to live on loathe, detest, abhor and hate the Catholic Church.
*How could all those Hollyweirdo live?
**How would all those living-in-sin (living together without marriage) feel good about themselves?
***How would all those on drugs and too much alcohol reconcile themselves to the word of God?
****How would all those same-gender "couples" live without being "married" to each other?
Those who would TOSS the ten commandments have made themselves the only arbiter of right and wrong. God and His laws (NOT the ten "suggestions") are meaningless to them. They are their own "god."
Boy, are they in for a surprise when their DAY OF RECKONING comes upon them. They will have to stand before their Maker and be judged...for ETERNITY.

Won't be pretty.
We’re never taught that clergy (including bishops, cardinals, or Popes) are perfect; I always bear in mind that Judas was a priest.
