Yeah it’s very sad when the yetzer hara gets in the way. My teacher showed us a handwritten note of the Rebbe when I was in high school, that said (in yiddish) “The yetzer hara saw that Moshiach is almost here so he laid himself across the threshold of the doorway, and sought to create machlokes… And rachmona litzlan he succeeded.”
Although interesting you mention the small breakaway kinus because just this year, I saw a video going around on WhatsApp that looks like the main speaker was calling for an end to this foolishness and that chassidim should all learn the sichos (talks) of the Rebbe together, and work together to discuss the best way to implement it.
