As a father, i have to admit..

I would have cut the husband's dick off and made the wife eat it.

Before making a bonfire from that table and then burning their faces off to molten flesh with it.

Then i would REALLY get medieval after that...

It would involve a bath of salt and a freshly peeled family.

Even after all that, the pain they would go through would not come close to the suffering of knowing your own child was mentally tortured to the point of taking their own life.

I wouldn't want her locked up for bullying - i'd want her walking the streets and freely available.
