What are these punishments?!?!?!

Excerpt 6 from Burchard of Worms describes over 20 examples of witchcraft and magic and their respective punishments. While the crimes range from simply following a crow and reciting incantations to find herbs to eating people and staking mothers and babies, the punishments don't vary as much. All of the punishments are 'do penance for __ number of years/days on appointed fast days' sometimes specifying bread and water. There does not seem to be any distinction between crimes that harm others and crimes that give guidance from others who are not God. There is also no distinction between believing and participating in magical activities. Simply believing in their power is evil. In example 60, Burchard makes no distinction between letting a magician into your house voluntarily to either except aid or to avoid any tricks. Even when you try to do something to protect yourself from magic you still need to pay penance. But oddly enough magical crimes surrounding women have similar punishments to crimes that don't. It's easy to believe that women are always punished more severely just for being a woman, but Burchard does not make vast distinctions. When you think of witchcraft punishments the typical witch trials and burnings come to mind, not penance on bread and water for forty days.
