For all the horrible things Poes foster father has said to and about him not once could he actually say he hated him. He didn’t. He disliked him, didn’t feel comfortable around him. But not once did he hate him.
Poes father liked to yell a lot, he was loud he voiced his opinions without thinking of what might happen, Poes father wasn’t a coward he stood his ground, and he was a strong willed man. Poe admired that about him, but that didn’t mean he loved him either.
He didn’t like how he treated him, even if it was his way of showing he cared, his words just came out harsher than intended. Poe knew this. Poe didn’t blame him though, he was raised that way. Poe also didn’t like how he spoke to his mother sometimes. It was also harsh, his father would end up apologizing sometime later but that didn’t mean Poe liked it. He also didn’t like how he was so quick to judge others and criticize them but never take criticism himself. But that didn’t mean he hated his father.
The day Poe found out his father had died he didn’t know what to feel. Should he mourn? Feel like it was a strangers death? Act as if nothing happened? One would think with the way his father treated him he wouldn’t mourn, but he did. No matter what his father had told him it helped him, in some sort of way. The criticism helped Poe grow and he was grateful for it. His father helped him with improving his writing even if the methods seemed a little harsh.
So yes, Poe thinks he has all the reason to mourn the death of his father. He raised him as much as his mother did. They had different methods but they both did raise him. He’s mourning the loss of his parent.
He cried that same night he had gotten the call, he cried because he didn’t know his father was sick at all. If he did he might have called or maybe gone to see him in the hospital but it’s too late now.
Poe went to his fathers funeral, he shed tears there too. His mother went, if he didn’t know how much she loved him he would’ve been surprised. They mourned together.
One mourning the loss of a father, and the other the loss of a lover.
After Poe went back to Yokohama he hung up the only picture he had of the three of them smiling.
Although Poes father could be an asshole he wasn’t the worst man to ever exist. He had his good times, and he had his bad times. He wasn’t the nicest but Poe wouldn’t have want anyone else to have been his father.
So no, Poe doesn’t hate his father, but he doesn’t love him either. He dislikes and he likes him. And that’s all there is to it.
