>Path 1 can't be Maou. If it was, path 2 would be heaven, and no matter what it says, path 3 would be telling the truth about not being heaven, hence it cannot be Hell.
>Neither can Path 2. If it's telling the truth that path 3 is hell, path 3 would be telling the truth about not being heaven, which is impossible
>What if Path 3 were Maou? It would be truthful that it isn't heaven. In this case, path 2 cannot be heaven as path 1 asserts, because this would mean the Hell path is telling the truth. So it would work if...
Path 1 = Heaven (lying)
Path 2 = Hell
Path 3 = Maou
Q.E.D. try making it a little harder next time
