This man should be sterilised so he never has another child

All over the world, if a parent does such a thing, he or she should be sterilised so they don't bring anymore children to the world to be abused by their own parents:

This is the horrifying moment a father dangled his young girl from a sixth storey window following an argument with his wife in China.
The man’s neighbours called police at around 10.30 in the morning after spotting him sitting on the ledge of his apartment window, holding his three-year-old daughter with one hand.
It’s believed the stand-off was sparked following an argument with his wife.

So, fight with the wife, take it out on the children. The same goes to wives, who after a fight with the husband, take it out on their own flesh and blood.

The couple had reportedly only recently moved to the new apartment in China's Guangdong province.
The man occasionally supported his daughter with one foot, but for the most part simply held her with one hand.
Emergency services arrived on the scene, with firefighters setting up an air cushion beneath the girl, while police made their way inside.
They attempted to reason with the man, but then rushed at him and pulled the girl inside.
The man was arrested by police, it’s believed he was under the influence of drugs at the time. 

Under the influence of whatever or not, this man is guilty of putting the life of his daughter in danger, and should be made an example of so others may take a hard look if they contemplate doing such a thing to their children.

Total depravity.
