What is the Difference Between What is "Good" and What is "Bad"?

Perhaps, since what is a "good" for one person may be a "bad" for another, perhaps the question why should society bother to distinguish the "good" from the "bad" in the first place? Is it essential for society to define the differences in order to set standards acceptable to society with regard to individual behavior to prevent chaos: a conflict between persons who find one behavior to be acceptable and the other persons who find it unacceptable? And yet, one might wonder whether society, perhaps through political decisions and laws, are setting too many standards, too many decisions as to what is good and what is bad, perhaps more than what is really needed.  Actually, I shouldn't be blaming society in general since each individual in society may live their life with their own stereotypes of other's behavior or their own life experiences or possibilities as either good or bad. And these stereotypes may not be based on facts but more on feelings or moral beliefs.  What do you think? ..Maurice.
