Space is deformed all the time according to gravitational waves. You don't notice it because you're in it and you are deformed with it, and your perception of it is scaled along with that. Space is not "destroyed" (why would you even think that).
If I struggled to the end of my determination, to the end of my way of life with my followers, if the result is ruin, then this ruin is inevitable. Grieve. Shed tears. But you cannot regret.
