I'm a therapist and my best assessment is he has antisocial personality disorder, with more diagnostic features leaning towards sociopathy, rather than psychopathy. He is not cool and calculated like someone with psychopathy. He gets nervous and will become angry or agitated easily. This presents with volatility and fits of rage. Criminal behavior (or in context the stuff he's done so far from day 0 to now) is rarely to never methodical, but disorganized, haphazard, and spontaneous.
He absolutely fears loss of control. This is clear from the Ronversations, as he freaks out and lashes out at Nick when he is feeling his control of the situation slipping, and will try to cause Nick to get upset by his parroted lines and repeated lies. In his mind, he continues to reinforce his perception he has deluded himself to believe each time he tells the lie. Even when he is challenged with contradictory evidence, he contorts himself to fit within his lie.
Even if Vic wins completely, Ron will never admit he is wrong. The way he minimizes his history of emotional and physical abuse, claiming he is reformed, but anyone who has ever had to go through DV/batterers intervention knows you never try to minimize like that, you accept full responsibility for your actions.
This and some other evidence I've seen (like the recent livestream of him and Monica), his multiple divorces and serial relationship issues, tells me he struggles to form attachments. He likely doesn't feel emotions, his emotions he appears to display are likely him mimicking. The Livestream videos where he constantly looks back to Monica, is a way for him to verify he is displaying the "correct" emotions to match the situation. Compare this to the deposition where his anger and desire for control rears its head with his responses and snarky comments. He tried to but failed miserably to control the situation.
Ron, from a literal professional therapist, seek help. If you already are, either they suck, misdiagnosed you, or you didn't tell them the truth. Your behaviors are deeply concerning and I would have valid reasons to fear for the safety of those around you.
