At the end of the day tho, Oscar has nothing to live for. His reputation is destroyed and he'll never be the man he was. I heard he's had a long history of depression b/c of his legs, I can see dude prolly committing that after some years. He can hide in South Africa for now b/c of how ignorant the upper class might be but outside of that anywhere he goes he's a disgrace and a loser.
It was really the prosecution's fault, they got excited and charged him with premeditated murder - of course that shit wasn't planned. He was on a roid trip prolly drugged out of his mind & depressed and went on a rage when he heard furious knocking at his door, thinking it was some African thieves and fearing for his life, out of his mind drunk with fear, depression and antihistamines, he took his gun and shot at the door multiple times hoping to ward off the thieves/killers. Yall gotta remember with murder, in most places they have to prove there was an intent to commit the crime beyond a reasonable doubt with consistency to what the prosecution is charging. If it's premeditated they have to prove he planned it before hand - which he likely didn't. That's why he got off. An amateur's mistake that was the luck Oscar needed to get off.
Culpable Murder is a better chance but with that they have to prove that he was morally and/or legally responsible, and if he already beat premeditated culpable murder is going to be harder to prove. If his lawyers are sticking with the "roid-rage-didn't-know-who-was-at-the-door" story he can't be proven morally responsible. The prosecution might try him for manslaughter but if he beats the culpable murder charge he's teflon.
