7 year itch

To borrow an oft used blog-line, this is seriously, sickly WTF.

A father, who killed his budding table tennis player son for not measuring up to his grueling standards, was sentenced to seven years in prison by a West Bengal court on Tuesday.

I mean, what. the. fug.
Isn't to screwed up enough that he killed his own son, and is obviously messed up in the head; but someone explain to me what the hell is he getting only 7 years for? No, really- go on, read the whole damn report and please convince me that he deserves only 7 years for outright murder.
