There is no such thing as right or wrong, because something may be right this moment and it may not be right the next moment. Something may be wrong today and may not be wrong tomorrow.
Right and wrong are not fixed entities, they are not labels that you can put on things, "This is right" and "This is wrong." But this has been done up to now. Right and wrong have been decided by people. And because people have decided right and wrong, they have misguided the whole humanity.
