A question arises of what does this world look like to the angels and holy souls above, in the real world?
Well, the answer is quite simple. You know that prologue, John 1:5 from the Bible?
“The Light shines in the darkness, and the darkness has not overcome it.”
“The Darkness”. That’s what this world is, and that is how it is known.
Since S.K. has been dead for a while why is existence of this place being prolonged?
Because the contractually agreed time has not yet expired. Sanat Kumar's life is in no way bound to the existence of this place; it's maintained by the Jewel, according to the will of God expressed in the original contract. Believe me, I tried to shut it down in so many ways. For instance, I tried to revoke the contract by stating that his permissions were authorised on fraudulent grounds, meaning that he didn't intend to do what he stated, but this argument was not accepted since Sentinel was aware of his intent and nature and approved the contract regardless, and since he had authority given to him by God, none can dispute it.
I also tried to revoke the contract, based upon the premise that since all original "signatories" are dead, it ought to be dissolved. This was also rejected, based upon the fact that the authority of the contract stems from the word of God, and not from either of the signatories.
Furthermore, I tried to argue that the foremost principle beneath anything is not the word of God, but dharma, meaning alignment with the inner nature of God, and this entire thing is fundamentally adharmic and should be dissolved on the grounds where things that are inherently opposed to the nature of God should not be allowed to exist. This was also rejected on grounds that although God in His nature of sat-cit-ananda is indeed the supreme principle upon which everything is to be built lest it crumble into non-being, existence of things opposed to God is not forbidden; it is just a bad idea and very much discouraged, because it can lead to terrible disasters such as this one. The terrible consequences, however, will not be denied to those who choose against God, and saving them would invalidate choice and freedom which are inherent to the nature of the soul. So, albeit this place is indeed a terrible nightmare opposed to God to the point where it would simply not exist were it even a bit worse, its existence is temporarily allowed, because eternity in God, salvation and blissful fulfilment are not obligatory, nor can they be imposed. This implies that terrible suffering, perdition and ruin are a viable alternative and can be chosen.
I used other arguments as well, but I was essentially told that God was smart enough to limit the existence of this dark pit of doom by imposing a termination date, and many other measures were put in place in order to assure orderly termination with the least possible amount of harm, and foremost of those measures is my incarnation here.
I might be stupid, but this is inconclusive for me, I mean does this shithole looks exactly like shithole to angelic and even more profound spiritual being in 1:1 ratio as it does to me when seeing all kinds of evil happening around me. I mean, I guess for anything above angelic level this should be considered as satanic but for angels I’m not so sure, I guess that sense of God’s bliss is enough to make them partially blind about the true nature of this place.
Well, let's put it this way, to a being that's accustomed to being in a darshan of God all the time, and that's a normal thing, this place looks the way Shelob's lair would look to someone who's accustomed to Lothlorien. The defining characteristic of this place is literally spiritual darkness, despair and separation from God, which is very close to the Christian definition of hell.
