What purpose would that serve? As Zevists we think practically. If it's an *extremely* evil person who cannot stop harming others, then it's best to use a death spell. A permanent curse can't stop such person in any way.
There have been many questions today about impractical curses and I wonder if you are spiritually experienced, adept at white magick and used black magick before. If not, you should focus more on your spiritual advancement and practice before thinking of any curses. I don't know, but I'm getting the impression that all these questions are all asked by the same person, a newbie.
