I’m not going to get involved in this conversation and certainly not about specific people but I will however say over something that Rav Yaakov Kamentky said in a smooze in Camp Ohr Shraga at a time of controversy.
“If there is a difference in opinion between me and the Satmar Rebbe whether a specific person is a Tzadik or a Rosha then just go with the opinion of whoever you usually follow because it is probably an underlying haskafa question based on Mesorah. If however despite our similar haskafa and upbringing there is still a difference in opinion between me and Rav Moshe Feinstein whether someone is a Tzadik or a Rosha then no matter who your Rebbe is and what he told you STAY AWAY FROM THAT PERSON!!!”
