Morality

What is morality? Is it something we should really follow? Who made these rules? I dont think I'm in the position to judge any entrepreneur about how they make their money. I mean of course scamming is not the dream job, but in this economy alot of these persons had no choice. Should I look down @ a prostitute if she sells every night to make her sons go to school everyday? Society and religion has altered and created the rules of morality but I just dont think it is fair to judge other persons. Everybody has to go on a path, not because their path looks different from yours, it doesn't mean its wrong
