Loxuru, you are partly right, and partly not.
It is absolutely true that, by far, the worst ratio of death condmnations for witchcraft, especially for women, was recorded in anglican and protestant countries, and not in catholic ones.
But death punishments by fire or beheading, hanging or slaying (mostly) in catholic countries have been recorded too, during a long period of time, until XVIIth and more rarely until the first half of the XVIII century in France for instance .
In these latin roman catholic countries, the "instruction" was made mostly by inquisition officers, often very seriously (by the standards of times, of course, but hard tortures were not systematic, a contrario the general and wrong opinion on the Inquisiion times,) then the trial and the punishment was decided by a royal court.
In those times were the religion was a matter of State and everybody had to be a loyal roman catholic, sorry to consider that your statement on ensuring that the church had no right to prounouce death sentences is a little "jesuistic", directly you are right, but undirectly a severe instruction by the Inquisition led often to death (not always by fire).
And, right, repentence was possible, but it didn't automatically withdraw the death penalty : sometimes you could be banned or go to a convent (lucky ones !), but sometimes you could end beheaded, stangled or hanged. Much quicker then the fire, of course...
