Have you ever considered...?
...the difference between good and evil.
I would argue that it lies between the realms of perspective and nature. If you boil it further to the core, it may be considered to be a nurture versus nature argument. Still moreso, one might say, as some have once said, it is neither good nor evil, but merely life that exists, and then does not. Our perspective may make it such. Or our eyes, shrouded in darkness, others would contend. Still moreover, their contenders would portend it be right and wrong; obstinately, they would claim to know what ought and what not, but then sow seeds of self salvation's, uniquely different across the heavens' gods. And then their perspective a question called into being by those who know no Being, or greater cause, nor sure salvation: cold, rather a distant temperature deeper, darker, colder than ever felt or imagined in the more terrifying of the mind;s creations. Cold is all they know and will ever know, for living to them is but minutes and years; once gone, they are gone, once dead, they are forever no more. But that is my perspective on those who believe there is no more after there is. Life: the difference between good and evil; both the creation and destruction of life is good and evil, for without life, there is no good, for without life, there cannot be evil, for good makes evil so and life brings good into this world. Therefore all is relative to itself, with regard to life, that is, all of life cannot be without the rest, and the rest cannot be without life.
