hey swami, that's a good point. People would go out and kill all the people they've hated for all these years, or go and kill all the guys who they are jealous of, like guys who have money, nice wife, and just living the great life.
It's sad but true. There will be some people out there who would say.. hey, if i am going to die in 4 days, why not take my ex girlfriend with me, and 7 other enemies of mine. Why should they live and continue on enjoying life,while i have to die.
This world would be chaos and you're right, people would be killing people on the street left and right, because it's not like they're going to prison for it.. They're dying in a few hrs anyways..
