Mikasa's Isayama says, in the manga/anime 'Attack on Titan,' that she can go for eating Eren, take a different approach. Many fans felt their hearts ripped out and threw them into chaos when she turned to murder him. It's a moment of real depth, based on years of shared history and great love. Eren, once the passionate standard of freedom and revolution, has reverted to a domineering Titan whose every move will be devoted to ensuring the snuffing out of all life outside Paradis Island. Mikasa, who has been both a childhood friend and worshipper of Eren, finds herself entangled in the paradox of love and understanding. While her heart tells her to protect Eren, her mind warns her to stop him. This could cause a disaster on an unimaginable scale. His decision is not because he has suddenly developed hatred, but from a smoldering realization that there’s helpless to deal with this sort of carnage except by removing Eren from the picture itself. This is an example of Mikasa’s courage, but it’s also a deep and basically conflicting emotion she is pressed by. It’s not betrayal, instead it ‘s a mournful elegy for the friendship that they once shared and a way of fulfilling her own role in this turbulent tale. The gentle kiss she places on Eren's lips in his last moments is an eloquent testament to her eternal love for him and, despite whatever despair may lie off there on the horizon.
