Why did Martin Luther criticize the Roman Catholic Church?

not not really, Luther was originated to the priest hood in 1507

The popes were very corrupt at the time and opressed the people most did not know what went on in the walls of the vatican. The pope around his time liked little kids so he had famous artist make naugty statues of little boys having sex. Another pope had a mass amount of prostitutes over one night. I should know I was there.

anyways there you have it ask yourself would you criticize this I would.
