It's sad that this Hasidic predator, Menachem Stark's life was ended before he was able to repent of his reportedly voluminous crimes. But the real tragedy is that this community is far too entrenched in a religion of megalomania, paranoia and hostility towards outsiders to learn anything from what happened.

They will still wail that any consequence or reaction to their criminal behavior is based entirely in 'hatred of Jews simply because they're Jews.'
