Magic Users
Personally, I would be uncomfortable with it because the intent is good but the risk of it then being used in a purge should the wrong people get it is troublesome.
From what I have seen, it is intent and the way it is used. While some claim there are types, in the end it is choice. Which could make complications. Especially once the varieties of magic are taken into account.
Of course, technology is not something I am used to, so maybe there are ways to work around those issues. I don't know.
