Another cool Harry Potter Healer idea
Anyone can practice healing magic. However those who become actual healers/mediwizards traditionally make a oath. Like how muggle doctors take the Hippocrates oath, healers take an unbreakable vow. This vow is called the Asclepius vow.
This vow is to heal the sick to the best of their abilities, never turn away a person in need, and most importantly never use your abilities to kill another human being.
Not all healers take this oath, but if a healer chooses not take this oath, they are looked down upon by the rest of the magical medic community. A healer who doesn’t take the vow is a sign of a bad healer.
Like with all unbreakable vows, if a healer breaks this vow, they die.
Also if someone took the Asclepius vow, they would die if they took Voldemort’s dark mark. Since the dark mark is a perversion that breaks the rules of the Asclepius vow.
