I stand corrected. Nevertheless, there is plenty of historical evidence for stake burnings across Europe on both sides of the religious isle. Certainly, more witches, per se, were burned in Protestant countries than in Catholic. And if I really wanted to expound upon the horrors of the Reformation, I would not have to go the the religious wars it spawned, but rather, just to Henry VIII's England. What a pig he was! In five short years he destroyed what 1,000 years of Catholicism had built: 1,300 abbeys, priories, nunneries, free chapels and hospitals, none of his actions supported by the people (unlike Germany). He was opposed (See: Pilgrimage of Grace), and thousands of people lost their lives, thousands more their livelihoods.
A larger point worth making, too, is by asking this: which church, today, takes a strong stand against any form of capital punishment? Only one that I know of.
