I made My point very clearly. please read my previous posts carefully. I will summarize briefly. We know it is possible for great people to go off and the depths they can go to Is limitless. We therefore must establish criteria by wich we would know if a once great person went off. My best criteria would be if a broad consensus of gedolim said that a once great person went off. It is extremely obvious that if the Lubavitcher rebbe would have indisputably said “I am mashiach” a few decades ago and not under duress that a broad consensus of gedolim would have paseled him. I am making this point because many fellow Lubavitcher’s seem to think he is mashiach because he said so(I understand that you dispute this last point).
