Just imagine little piggy's childhood. He kills the dog of another kid from the school. Kids parents find out, they notify the child, word spreads around the school about brutal death of the dog (police may or may not have been informed). Parents discretely talk about it. If not before, now the entire community knows that there is something terribly wrong with piggy boy that hung the dog. They know his brother is retarded, They know his father is filthy alcoholic violent piece of shit, and it's obvious that family circumstances are such that piggy will not change for the better. At the gentle age of 8, everybody knows that there is no hope for little piggy. 30 years ago he was judged as done for. They caution their kids to not play with piggy, because he'll at best be bad influence, at worst...? They don't even want to think about worst that can happen. Nobody invites piggy to birthday parties no more.
Everybody avoids him and the rest of the family as politely as possible. Little piggy, ostracized, unable to make friendships does the only thing he can and starts flirting with the little piglets that didn't listen to their parent's advice. This is "our group" he said other kids were "fucking with". Probably pointing fingers at them mocking and teasing them for being uncivilized and deemed worse than animals by their parents. Just like Kiwi's are doing to this day. He tempts his group of bullies to do nasty things and learns to leverage it. He knows every kids dirty secret. Just like to this day dirt on people is the only thing he relies on.
Parents were right. There was no happy ending for piggy. 30 years have passed and piggy is still in that same old cage he built when he was only 8. This is a person that never experienced joy in his life. And i'm fucking glad to know his entire existence is so miserable. And now we know that every time we point and laugh at him he hears 8 year old kids mocking him. It never stopped.
