Is it a loop? Daniel Faraday crying in Season 5 suggests that. Something hidden in subconscious terrain. Dark Tower? Makes sense so far as something mind boggling like that is able. Why can Hurley see dead people? Things are out of bounds--supernatural play. Mix of religions and mythology, etc? A straight rip-off or entirely new? So many questions. Good and evil seems obvious...but what is good and what is evil? Isn't that all relative...to each person or entity? Don't people/things who want what most would deem bad only want it because to them it is good--like reaching the good through a skewed method? I think C.S. Lewis said something like that. And hey, C.S. Lewis is referenced with Charlotte. Lots of renowned thinkers are referenced for that matter. I know everyone knows all this, but I'm just gathering thoughts.
