♣ KORRA: No. Definitely not. Her entire existence is way too caught up in the role of the Avatar and in the natural cycle that progresses for her to lay down her arms and accept defeat in being stuck in Darrow. The only potential way that might change slightly is if she gets time to speak with the first Avatar and understand the contrast before and after he took up his role; if he thought that the world could survive without, she might reconsider. But at some point, it's also not really about whether or not life would move on without Korra at home, it's about what would be best for the world, and Korra fully believes that her value as a powerless individual in Darrow is far less than the value of getting a new Avatar back home. If she really felt hopeless about going home, she'd honestly sooner end her life for the sake of her people and her world (as evidenced by some near choices of hers in canon, too).
