What do you catholics think about the doing of the Pope at the middle ages ?

First off your History is flawed and reads like a protestant version of Church history. Many non Catholic Historians now admit that the sins of the Catholic Church were greatly exaggerated . The inquisition was nothing like your suggesting and most of it was Political and done without the Churches permission.The best estimates now being used of deaths are at a maximum much less than a Hundred thousand over the years it went on with the Pope's condemning most of it. As for the crusades most historians now agree it was a defensive action that was needed to protect the western world. So i would have ume by your question that your either a troll or have poor historical knowledge.
