And in regards to that last paragraph, what I wonder is, whether those who so vividly wish to call Sauron evil, will find this has also implications for their own
What I mean with this is:
If we deny Sauron the right to enslave, kill and rule beings that he -as a devine entity- could very possibly view as inferior creatures, then how can we justify enslaving, killing and ruling what we commonly refer to as 'animals' in our own world? If we believe he was doing wrong, then must this not ultimately lead to us reviewing our own postition on how we treat creatures we consider 'inferior'? The argument that we can think can not be used, as Sauron was able to do things beyond the abilities of the 'races' of Middle Earth too. René Descartes view was that animals were only 'biological machines' with no true feelings, and therefore the pain responses they displayed were automated and not truly 'felt' by a soul they were lacking in his opinion. Sauron could theoretically have had his own theory on those he enslaved, killed and ruled, as well. I think it was Curandhras who suggested something like Sauron could have been looking at it as to where is the big deal, they enter some form of afterlife and it doesn't really matter what I do to them 'here'. (This obviously differs from Descartes, but it isn't about Sauron sharing Descartes view, but that he could have had his very own theory in regards to 'inferior' beings).
If we only take the step of condemning Sauron and calling him evil, then would we not be hypocritical if we'd not take the next step of calling what humanity does in regards to its fellow inhabitants of this planet, evil too? And if we do not wish to be caught a hypocrite, does that not also mean we have to try our outmost best as individuals, to distance ourselves from actions which will include or lead to the enslavement, killing and ruling of other 'inferior' beings?
For if we don't - how can we judge Sauron..?
