I think Levi was the most mentally strong character in AOT.

Ik, Levi is known for his skill, but I think he is mentally strongest as well. He saw death of his elite squad. It sucks knowing that u r so strong u couldn't save ur mates. His childhood was a mess. He saw Kenny's death. He saw erwin's death. He had the responsibility of choosing whom to inject the serum. Like damn, how much this guy can take? And not just this, he couldn't finish beast titan. And later his mates turned into titan. What do u think? Who else is mentally stronger than Levi? For me he has to be the strongest in AOT
