That is what I was referring to in my bracketed paragraph. The writers did a poor job at committing to the necessary scale of devastation that had to be inflicted upon the alternate timeline to justify the "it's so doomed we had to rewind and try again" outlook that the story relies on. It should have been as simple as Black Rose killing everyone in its path, ever-spreading and unable to be halted, and the few remaining survivors send G'raha back in time before they too succumb to inevitable death.

Instead, the writers hesitated first in how impactful Black Rose was, added in the contradictory secondary premise that humanity was not only mostly wiped out but also retained enough manpower to wage endless large-scale war in the aftermath, and ultimately is all set to move forwards after they've just wasted years of effort to throw away the Crystal Tower instead of regarding it as a very valuable resource and spending their time on better world-fixing innovations.

But as I said, that's poor writing and I am inclined to separate it from the clear intention to portray the world as doomed and unsavable, because the plot relies on that premise even if it was sold badly.

Every time G'raha has talked about the people he left behind in that world, it is very clear that he believes they were doomed and he is sad about what he understands to be their fate.
