What gives them the right to hold their society superior to what the star created?

The continued existence of their loved ones and society combined with reversing a situation that was inflcited upon them at the behest of a very unwell and deluded woman in the form of Venat. Let's not pretend as if she wasn't the one who forced the Ancients into the predicament in the first place by refusing to mention any of the information she had been entrusted with.

There's no benefit to criticising the actions of those seeking to do whatever is necessary in order to survive if they are deliberately forced into a corner. As if they have any need to just roll over and die for the sake of someone else.
