Why didn't Levi kiss Erwin after he chose to let Armin live, the titan curse could have been lifted right there. Erwin was a devil that was sending hundreds of new recruits to death, and Levi was a loyal Ackerman. Their bond is as strong as the bond between Eren and Mikasa. If Levi had kissed Erwin at that moment, then Ymir would be happy and finally let go of her love for the first king.
