Um no. Being a resposible adult, father, role model, is not only getting yourself out of the hole you've dug. It's also standing there with a club, looking down at a bleeding dog after you've hit it the first time, and thinking "you know, this is wrong. Maybe I should quit before I get caught."
One mistake? ONE. Perhaps you haven't read about all the charges filed against him, and all the terrible things he's done. And, yes, if I become a mass murderer and run around brutally killing animals, I hope people hate me forever. I want a constant reminder for the rest of my life that what I did is unforgivable.
The man is already trying to get another dog. Are you kidding me? Because his children are sad they can't ever own a dog. He cancelled on Oprah for fear of meeting one of the dogs he terrorized. I don't think he can face what he did. He just turns his back and says i'm sorry. Oops. Running to the arms of people who forgave him. It's ok, cover his eyes, let him think the past is past. Sooner or later his evil side will show up again.
