wrong and right?

who's to say whats wrong and whats right? why should should a government base there laws on rules of one religion, when 99% of nations are multicultural. what do you consider right and wrong.....? does it line up with your nations laws, and if it doesn't does that make you an anarchist? my personal view is that something that is "right" is something that benefits your life in a positive way..... yet doesn't affect or harm any other living thing directly in a negative way. So by this definition eating junk food or smoking is morally OK. But blowing smoke in someones face... is wrong. which brings in to question the topic of context. in what context can different actions be right or wrong? let us know whatyou think in the comment section below.
