Depends on how well Bruce can cover up his retribution. Abusing his power like that could easily develop into a scandal or be outright illegal enough to not be worth it.
Bruce also isn't known publicly for being hyper competent or being caring about his son that just about noone has ever fucking heard of.
Outwardly Damian's basically the perfect target. He has an uncaring dad that would probably just toss money at an issue while Damian acts like a shithead for being neglected by daddy. He's a scrawny midget, rich enough that he can be extorted far beyond normal children,enough of a shit that people won't feel bad for him and if he hits them back they can sue for a big payout by overreacting to the injuries,
