This lunatic, talks with confidence as if he spoke to G-D himself! There is absolutely no source to his idiotic comments in the entire Torah, Shas & poiskim!
Some may say that this may be kabbalistic .... and that the Zohar HaKodish writes about it, however, the Rambam does not agree at all about the concept of Gillgulim or re-incarnation ....
However to talk publicly to parents or siblings of Autistic or Down Syndrome children and tell them that their children were evil in a previous gillgul ..... is cruel and sadistic!
There is no hell hot enough for this meshiginar!
