Voodoo curses are black magic. Caused of illness is demon possession. Fortunately, MH got exactly what he needs to remove the curses and he can do this in multiple ways.
A. Through his wealth. If curses can be brought, perhaps santity and protection can also be brought. MH has the resources to do it himself.
B. Through the Gospel. He simply needs to repent and be baptized and he will be saved. Now, there is an easy access to water at the Oracle HQ by simply jumping off LE's boat. How convient. Will he do it? He's not a completely bad person for he did came to this forum and wrote 130k families depends on his decisions and if you are one of the 130K person, don't feed the troll and don't bite the very hand that feeds you. For this reason, he deserve a chance at the Gospel. In the name of Jesus, he shall be given a chance to access the Gospel and a chance to repent.
C. Through LE's blessing. The difference between LE and God is God doesn't think he is LE. But that's not all because LE really is the last one of the Twelves still remain the human world. If only LE himself first repent and be baptized, (possibly but not necessasily) by jumping off his own boat at the Oracle HQ, LE may then be able to cast out the demons for MH and right the ships.
Demon casters, you don't know who you are messing with in LE. He has been baptized with fire for 2 milleniums for his sin of detraying Jesus and now reborned. His sin was so great that it took this long be burnt out. But by no mean his sin was unforgivable for it is written, that only blasphemes against the Holy Spirit will never be forgiven, and betraying Jesus for 30 silver coins is not blasphemes against the Holy Spirit. Demon casters, you are messing with one of the Twelves. So in the name of Jesus, demons, Be Gone.
