Soooo.... two people were murdered and the murderers were arrested and charged with murder. Why do you hate india now?
It's not like anyone goes around saying "OMG, that one dude in the news beat and raped his kids and when the cops came he murdered his family! America sux! Stupid."
A handful of crazy hicks do not a country make. Now if the family got away with a slap on the wrist, I would understand your concern. But in this case, the justice system works there just like it works here... murderers are captured and punished. Hopefully these crazies are, at the very least, put away for the rest of their lives.
If you're going to hate a country, hate it for something involving the population as a whole, the conditions, the government or justice system. Do not hate it because it has some freaks that aren't condoned by anyone.
::Edit:: Also FYI, LOTS of young kids elope in Indian nowadays. And just like here, the parents very often don't approve. However, they generally DO NOT go around murdering their children out of disapproval.
