Joan and Wallace and Savanarola were political executions using religion as a mask. Remember that the Popes were temporal kings at this time. Doesn’t invalidate the point. It wouldn’t surprise to find that most of the deaths in the Inquisition were to acquire property or settle a grudge.
Henry VIII killed plenty of Catholic for that.
