Seriously I wanna talk about Hardin for a second.
This man was probably one of the purest Heroes in the Fire Emblem pantheon. He liberated slaves and built a foundation for a nation with everlasting peace. He cared for his people, his country, his friends, his family, and all that good stuff. But the dude was depressed for all the things he did right, he couldn't do his marriage right. And it wasn't even his fault. He loved his wife Nyna with all his heart but she didn't love him back. She was in love with someone else. His depression ruled over him.
So what did Gharnef that mother ****** do? He corrupted him into an iron-fisted Tyrant and had him send Marth away right before his marriage so that he could take over Altea.
Hardin was one of the most pure hearted individuals who was stricken by depression because of his unrequited love and was corrupted into a tyrant.
"Prince Marth. I feel as though I've finally awoken from a long, long nightmare. Marth. Forgive me. I tried to fight the demon inside me. But I wasn't strong enough. I fought so hard, but I just couldn't beat it. I wanted to die by your hand and now I'm finally saved. Marth, please, Nyna. Save Nyna. Please tell her, tell her for me. Till the very end I loved her always. Tell her to please forgive me."
Seriously, finishing New Mystery of the Emblem hit me hard with that line.
