When making stuff like this they say to tell a personal story first. It sort of "gives you permission" to speak on these matters. All righty then:
I had my Dad in mind a lot when I made this. We're on better terms now than ever in our lives. All the bad shit happened so long ago and I understand why it all happened the way it did.
In brief, his dad (my grandpa) remarried when he was just a kid. His bio mom had gotten cancer and you just traded in for a new model back then. Pretty monstrous. Then she died after the divorce and he remarried to a woman who convinced his dad to exile his older brother from the family completely (I've met my uncle only once, and my cousin never). When the floor falls out from under you like that at the age of 10, yeah you're gonna marry a psychotic woman just like your stepmom, drink, break shit and scream at your kids at best heh. His "bad" wolf probably looks a hell of a lot more fucked up than this one.
Anyhoo. If you can forgive him, and get him to quit clawing at himself, then it makes things so much easier. He's waiting for someone to tell him that it's ok. Just breath and tell him he's a good boy. Cause he is UuU
