Contrary to the above (some, rare) Peonians IMC do carry out lethal sentences against witches when allowed by secular authorities
I don't think "allowed" is quite the right term. No church on Harn has the explicit authority to conduct trials and executions of ordinary people, except on church property to church serfs (in which case they are acting just like lords on a manor). Perhaps, "turn a blind eye" might be a better description.
Who are these 'witches' that are being prosecuted and executed? Is it all just hysteria and misconception, or are we talking about actual evil cultists? You can argue moral relativism all you like, but I'd be on the side of anyone burning Morgathians at the stake.
Well, witchcraft is simply the "casting of inimical spells", so legally it isn't much different than assault, except the punishments are usually harsher because the idea scares the s*** out of people
. Now, how many "witches" are just scapegoats for the rash of miscarriages in the village this year, the victims of hallucinations and tremors caused by ergot poisoning, or the contrived deus ex machina for a rescue adventure - that's definitely a p-Harn thing. And so is the number of real witches.
IMpH, witchcraft trials are uncommon, and the GoAL and some of the churches work to make sure that's the case. I think the Peonians are quite afraid of witch hysterias - as healers, they are the first to be suspected. Laranians and Agrikans are also somewhat motivated to keep the whole pitchforks-and-torches scene from happening.
(IRL, the Medieval Church discouraged witch trials, and the era of burning witches came with the Protestant Reformation, when the Church was weak and religious leaders were at each others throats.)
And I don't think that anyone disagrees that Morgathians are stake-worthy. I think the only point is that for Morgathianism to be credible, Morgathians must be able to perceive themselves as good. Only an ass would argue that the Khmer Rouge was not evil, but it is possible to understand the internal logic of the regime and why its members thought that they were doing right.
