I wonder if he's wild because she was so strict, and he's too retarded to learn. Like the moment she beat him, his stupid ass learned that violence is okay to use.
I don't think she was strict at all, quite the opposite in fact. It's why we saw him crying like a baby when the cops arrested him. He instantly started bawling and doing his normal routine of telling lies to avoid any punishment, and when he realized it wasn't working he started crying and pleading even harder for them to just let him go which then lead to him BEGGING Ed and Sally do DO SOMETHING to prevent him from being hauled away.
Remember that she wasn't upset with Chance when he raped Billy, she was only pissed off at Billy for telling the authorities which could and should have lead to prison time for the goblin. And then as he was being taken away in cuffs a few weeks ago she yelled "HE IS NOT A PREDATOR!" despite all the evidence that he is.
I get the sense that she knows what a piece of shit he is, but she'll never admit that he's anything but a perfect little angel, she thinks maybe one day he'll grow out of all this and start acting like a real adult in the real world. But that shit ain't ever gonna happen because she doesn't see herself as the reason why he's such a piece of shit just like his dad.
She didn't change his name to Chance because she was giving him a second shot at life, she did it because she sees him as her own form of redemption, guaranteed. She already raised one pedo piece of shit and wanted to not do it again. And she failed, epically, because she only gave him love and praise and excused all of his bad behavior instead of ever once using discipline.
I'll bet that she never said "No tv for a week" or dared to take away his toys as punishment. For fuck sake, he's 32 years old and she has to literally bribe him like a child just to get him to mildly curb his worst behavior for a short period of time. That's fucking insane to us because we're not as stupid as this family is, but to them it's totally normal and logical.
When he bricked his Xbox a few months ago, did she let him learn a lesson to not be such a god damn fool? "You did a stupid ass thing and now you don't have an Xbody anymore, quit your bitching and make sure you don't do it again". Nope. She conned someone online into buying him a new one because he wouldn't grow the fuck up and stop acting like a spoiled 2 year old.
