The link has been established many times, with serial killers especially, who started with animals in their youth, and later migrated to people. We, and others working on the “Cat Torture” issue have warned against the perpetrators in China and elsewhere (as this material is spread globally via Social Media) eventually performing that same migration. Obviously, that does not mean the animal abuse is negligible so long as it stays there. Far from it. On the contrary – as, it has been said many times before, that the more helpless a creature, and so a victim, is, the more deserving it is of compassion. There can be no more helpless party, in a human society, that largely denies them any rights and/or equal consideration in respect to freedom from pain and suffering, than an animal.
One such example, which I remember well – as I have seen the material (meaning: videos) at the time – concerning a now 42-year old native of Canada, is one “Luca Rocco Magnotta”.

He came to fame, if that’s the phrase for what he did, when he murdered and dismembered his boyfriend in 2012. He was eventually apprehended in Berlin, and is currently imprisoned, for life. What I remember him best for, though, is …

.. which, in 2019, was the subject of a “True Crime Miniseries”, called, “Don’t F**k with Cats: Hunting an Internet Killer“

This is but one of many, who started out on animals, and later tortured/killed Humans.
There are two publications on the issue that are worth reading:
“The Link: Cruelty to Animals and Violence Towards People“

and
“Animal Cruelty, Pet Abuse & Violence: The Missed Dangerous Connection“
It cannot be stressed often enough that the nice guy next door carrying the little old ladies’ shopping upstairs might be a raving pervert, spending his time torturing animals, and hatching plans to do same to people. Not all of them are as obvious as this one last year ..
