Sociopaths are made how they are; psychopaths are born.
That...thing didn't come from the type of environment that produces a sociopath. You need to see quite severe trauma--growing up in a war zone, very violent neighborhood or exceedingly abusive home. While his home was probably abusive, it was not abusive to an outrageous extent that involved severe beatings (the kind that puts a kid in a hospital at least once), a parent who routinely made him go to school dressed like a girl as a punishment, or other creepy/extreme abuse.
Like all psychopaths, he also exhibited signs of anti-social personality as a very young child: hitting a teacher, throwing rocks at an infant, being excessively physical with other children or even violent with them (he was a known bully, as a young child).
Sociopaths don't tend to exhibit anti-social behaviors like those until they're much older. With sociopaths, you'll hear from people who know them, "He was such a nice kid, and then something happened to him," usually when that kid became a preteen or teenager.
Nobody ever says that about a psychopath. They were never nice kids. They were always cruel, creepy and even violent. Just like that...thing. Over and over, we keep hearing what a mean, violent kid he was. And sometimes even he brags about how horrible he was, as a young child. After all, he's the source for the tale about how he hit a music teacher during a piano lesson. It never occurred to him that decent people would find that not cute or clever or funny, but horrifying. And the way he told it? He was bragging about being a vicious little monster, because he considers it a good thing to act that way toward anyone who thwarted him!
He's a psychopath. I can guarantee that an MRI of that fat pumpkin head of his will show a brain like the lower one, with poor pre-frontal cortex development.

The pre-frontal cortex controls executive decisions and a normal person's understanding of how actions have consequences. That's the part of the brain that makes normal people pause to consider how our actions will affect others or even ourselves. Psychopaths don't have that capability. It both makes them incapable of empathy and extremely reckless and impulsive in their actions, even to their own detriment. They just don't care about what will happen if they do X, because all they know is that they want to do X in the here and now, so go for it.
We need to call him what he is: A psychopath.
