Destiny has never, ever, showed regret about any of his actions, all his remorseful behavior that he has ever shown has either been completely performative or regret of having been caught. He sees people as play things, and genuinely gets angry at people calling him out or trying to tell him he did anything wrong.
This isn't a broken toy who needs fixing, through love and empathy like Erudite is trying to make it sound. This is genuinely an extremely manipulative and malicious person who doesn't appear to even show even the slightest amount of real concern or paternal instinct for his own flesh and blood.
The guy is a predator, there's genuinely no better word to describe him, and people should never give him even the slightest inch or relax around him, as he always capitalizes on any and every opportunity.
You can see it clearly, his first instinct, when anyone becomes aware of what he really is to cut, and silence them, he only looks out for himself and his survival for his way of living. And he will never stop, this isn't a person who can be rehabilitated, because he genuinely doesn't think he has, can, or will ever do, anything wrong.
If he ever tries to pretend that he's going to therapy and that he's working on himself, like I'm sure horse kick to the head girl will say, no one should ever trust him or believe him, as he is 100% only doing it so in the future he can start doing it all again.
