He's the kind of person who believes he is in the right. In his mind he was reacting to something (alluded to in his AI statement) that Gael had done or said. So it wasn't his fault, he was provoked
In his eyes the whole of the BD-universe is wrongly against him.
He's lost access to his son.
He will likely never work in super-yachting again, with convictions behind him .
I can see him swirling the drain, self pity and seemingly no way out of the legal stuff.
I hope I'm wrong, obviously. He's a piece of shit but I don't wish anyone dead.
