Why did the Protestants want to reform the Catholic Church in the sixteenth century?

A:

Throughout most of the centuries leading up to the Protestant Reformation, the Catholic Church had been wracked by corruption and hypocricy. The sale of bishoprics and other forms of simony were widespread, with occasional popes attempting with limited success to stamp out these practices. The sale of bishoprics in Germany, and the aggressive marketing of indulgences, partly to pay the debt incurred by those sales, were the trigger for the Reformation.
