Since right and wrong relative,they are defined by people based on their own mindsets.Something right to me is may be wrong to you and vice versa. Some thing right to peoples of a culture may be wrong to other cultures etc.For example(I don't want to criticize anyone's beliefs)having multiple wives is common thing in some countries(like middle east)and in some cultures and religions but it is a crime in some countries like our country(India) etc . So people define right from wrong based on their mindsets but those mind sets are defined by their social,cultural,economic backgrounds.From time to time these definitions change and what right once upon a time may be wrong today and what is wrong today may be right tomorrow.(for example mothers used to mate with sons in early human civilizations but today it would be intolerable crime(at least to me)).When cultural,social and economical changes occur many things change even food habits for example when we have money we will eat good food and eating out of garbage cans may be wrong but when we live on streets and hungry with no money we will try anything to satisfy that hunger even eating out garbage can is possible.so what I want to say is right and wrong are relational and both are a paradox they do not exist(but we have to fallow the traditions and customs of society we live in so we too define right from wrong as our society do that) do you think right and wrong exist?
