It was a perfect example of how worthless and subhuman and out of touch with reality Balldo is.
He intended it as making an example of someone who had entrusted something to him in confidence, thus betraying the confidence, and trying to humiliate that person with something given in confidence.
First, this basically was an admission that he is absolutely garbage as a lawyer. Who would hire a lawyer who would betray a confidence just over a grudge? So he started out by ruining anything resembling a reputation as a lawyer right out of the gate. Good jerb Balldo. Nobody would ever hire a fake lawyer who would do that.
Then he sadistically, but pathetically, taunted that dude about stuff he'd already gotten over. So he was gloating and taunting like an anime villain, but his actual "victim" didn't care any more. It was his intent that made this pathetic and disgusting, because he utterly failed at actually harming his intended victim.
And finally, and most hilariously, he did all this as some kind of "monkey on a stick" strategy of trying to threaten the Farms, like "look what I did to this guy, by betraying his confidence like a backstabbing cowardly traitor, I'll do that to you, too."
Except nobody cared. Bring it bitch you pathetic fucking faggot. You can't do SHIT to us. You fucking loser. We OWN you.
He made himself look like a garbage subhuman and his only win was he won our eternal enmity.
