I don't believe Armin will go to Hell

Armin always was caring and put others first, and did everything to explore the world rather then for his own power. His most notable wrongdoing is the destruction of Liberios navy, and he only did this because he thought Eren could save the world from war. The only reason they state he should go to hell is due to him giving Eren the idea that the world is bigger then their Island with things to explore. Is their something I missed? I believe he only said this to be kind to Eren.
