The Star City Ending since a Reddit member proposed that you can return to Vyn after the destruction,built a Beacon yourself and banish the High Ones once and for all.Then you do not have to try to play God,trying to achieve the impossible that is a humanity without Ego.(After all Ego has it's positive side).
Blackrock wrote:There's also the philosophical standpoint, as evidenced by one of the questions you can ask the Black Guardian. Just what IS humanity without an ego? That is an integral part of man's nature - just as humility and altruism are there, so too are pride and arrogance. Every character you meet during the course of the game more or less emphasizes that, yes, we as a species are flawed, but we are not irredeemable. I don't think that by playing God you can just erase that part of human nature, maybe at the start, but somewhere, some day, someone is going to give in to those dark urges and the Cycle will begin again.
Finally, consider this - isn't it completely arrogant and egoistical to believe that YOU are going to be the one to create a better, "improved" mankind? The very last moments of the game drove this point home, when I was moving to destroy the black crystals powering the Beacon and saw Tealor lying there. "I led them into the light, I alone..." he said, even at death's door his pride was everything. (such a tragic character, BTW) By abandoning humanity and being the one to "lead them to a brighter future" aren't you essentially falling into the same trap? Intentional or not, I feel like that was a really clever parallel. My point being, you can't stamp out pride and arrogance by essentially elevating yourself to godhood, that's not how it works!
So yeah, I feel like humanity has a better chance with the Sacrifice ending. It's not going to be easy and there will doubtlessly be many more setbacks and bloodshed, but at least with that ending people will have something to look up to. As Jasper says during one of your talks, having a symbol, an idea to believe can bring out the best in even the most cold-hearted cynic (like himself). The Prophet's sacrifice and the knowledge of what the Beacon does, I feel, is enough to tip the scale's balance in humanity's favour.
