Sounds like a cross between Jaden Smith and Dr. Bronner.
He likes to quote the wisdom of his father, who stabbed a man to death waiting in line for Santa at the mall:
He's also apparently prone to violence (domestic and otherwise) himself:

"Since I was a child of three or four," he says, "I was always wondering, you know, why does a bubble take the shape of a ball? Why not a triangle or a square? I figured it out. If Pythagoras was here to see it, he would lose his mind. Einstein, too! Tesla!" He shakes his head at the miracle of it all, his eyes opening wide, a smile beginning to trace itself, like he's expecting applause or an award. And all you can do is nod your head and try to follow along. He just seems so convinced that he's right. And that he is about to change the world. "This is the last century that our children will ever have been taught that one times one is one," he says. "They won't have to grow up in ignorance. Twenty years from now, they'll know that one times one equals two. We're about to show a new truth. The true universal math. And the proof is in these pieces. I have created the pieces that make up the motion of the universe. We work on them about 17 hours a day. She cuts and puts on the crystals. I do the main work of soldering them together. They tell the truth from within."
He continued to love himself by buying scissors, wire, magnets and vast numbers of sheets of plastic. He had a theory. It might seem crazy, it may even be crazy, but a long time ago he'd gotten hold of this notion that one times one doesn't equal one, but two. He began writing down his logic, in a language of his own devising that he calls Terryology. He wrote forward and backward, with both his right and left hands, sometimes using symbols he made up that look foreign, if not alien, to keep his ideas secret until they could be patented. In 2013, he got married again, to an L.A. restaurateur named Mira Pak, and the two would spend up to 17 hours a day cutting shapes out of the plastic and joining them together into various objects meant to demonstrate not only his one-times-one theory but many others as well.
After high school, he attended Pratt Institute in Brooklyn, studying chemical engineering, until he got into an argument with a professor about what one times one equals. "How can it equal one?" he said. "If one times one equals one that means that two is of no value because one times itself has no effect. One times one equals two because the square root of four is two, so what's the square root of two? Should be one, but we're told it's two, and that cannot be." This did not go over well, he says, and he soon left school. "I mean, you can't conform when you know innately that something is wrong."
He likes to quote the wisdom of his father, who stabbed a man to death waiting in line for Santa at the mall:
Leaning into the softness of the sofa, he continues, "My daddy taught me, 'Never take the vertebrae out of your back or the bass out of your throat. I ain't raisin' sheep. I raised men. Stay a man.' But being a man comes with a curse because it's not a society made for men to flourish anymore. Everything is androgynous, you know? The more successful men now are the effeminate." Which is another attitude that has gotten him heat. Not that he cares. "The people that judge you don't matter. They're not real. Everything is just frequencies."

Another problem Howard has is his temper. He's been escorted off a plane for unruly behavior. He's punched out strangers in a restaurant. He's said to have knocked at least two of his women around, most recently ex-wife Michelle Ghent, who after a 2013 trip to Costa Rica with Howard was photographed with a black eye. She said Howard did it. He either denies the allegations or shades the circumstances or has outright justifications.
