I think he was a cool pope. He died just a few years before Giordano Bruno’s death.
When he was elected pope he told the cardinals, – God forgive you, you did not know what you were doing.
And this what he did is trully amazing….Namely,
in a decree dated 18 April 1591 (Bulla Cum Sicuti), he ordered reparations to be made by Catholics in the Philippines to the natives, who had been forced into slavery by Europeans, and he commanded under pain of excommunication of the owners that all native slaves in the islands be set free.
He also had a nervous tendency to laughter, which occasionally became irresistible and even manifested itself at his coronation.
Finaly he ruled just one year.
Had he lived longer, I think no way, he would have let Giordano Bruno get murdered.
