Personally, I never could figure out what Yuno-1's end-game strategy was. As long as the game kept being played, she would get to be with Yuki and have her "one night of bliss" over and over again. But as long as the both were players in the game, she was stuck in an unending cycle of death and destruction. Always the chase, never any peace. She was insane, so doing the same thing over and over and hoping for a different result isn't out of the question.

Yuki-2, on the other hand, seems to want things to end, but wants to still have Yuno by his side, which is impossible. Unlike Yuno, he does not want to keep repeating the cycle endlessly. That desire seems to warp causuality in world three to prevent the game from ever beginning, ending the cycle. It's my belief that he's broken the cycle BEFORE Yuno stabs herself. With the cycle broken, Yuno stabbing herself was the only way for her to save Yuki. Muru Muru-1 storing Yuno-1's memories was fortuitous, in the long run.

As for all the death and destruction along the way, let's not forget that there were two worlds that had played the game, but we only saw the final outcome of the first. It's probably safe to assume that there was just as much suffering there. One has to wonder how different that world's game went. In the end, World 1 is gone, World 3 is missing it's Yuno Gasai, and World 2 has two gods recreating it together.

A postscript:

In retrospect, EVERYBODY on World 3 gets a happy ending (such as it is) and Minene-2 gets one (with Nihijima-3) as well.
