you all have no idea. I cite a recent example down the road from where I live IN South Africa, in fact very close to where I was born and raised.
https://www.enca.com/south-africa/two-men-plead-guilty-murdering-family-eightTwo cousins murdered an entire family including babies as they believed they were witches.
Most of the time these murders are drug and jealousy fueled disputes, which are ended when one of the protagonists drunkenly stumbles on the revelation to accuse the other of being bewithced and have them killed by their friends that same day. The other times the dickheads actually believe it.
Personally, I think that belief in witchcraft, not paying taxes, claiming benefit and omitting crime should logically exclude a citizen from voting, but hey, that's just my racist white privilege talking.
