Why are people so judgmental of those who commit suicide? Who the hell made it the law that you HAVE to live?

Who the hell made it the law you HAVE to go through all of life's hardships? Maybe some people relish hardships because it provides them a "challenge", but others see it as an unnecessary impediment to happiness. If they desire not to go through crap, why shouldn't they be allowed to end their lives? Just because you are fine with suffering doesn't mean everyone is fine with it. What makes you think you have the right to judge others based on how they see life?
