Indeed, there is no such thing as right or wrong, good or bad, should or shouldn't in the absolute sense. Because they are merely subjective judgments based on personal values. But you might ask, then why do the enlightened ones act, share, and think as if they know exactly what should and shouldn't be? And if there is no right or wrong, where would humanity go, if no one cared about right and wrong, wouldn't the world have perished long ago due to wrong human thinking?
