What did dobbins say he might do after the war? Why did dobbins say he couldn't be a real minister?

Dobbins thought about becoming a minister, but he said he could never be a real minister because he wasn't smart enough and hated going to church.

"But anyway," Dobbins said, "I couldn't ever be a real minister, because you have to be super sharp. Upstairs, I mean. It takes brains. You have to explain some hard stuff, like why people die, or why God invented pneumonia and all that." He shook his head. "I just didn't have the smarts for it. And there's the religious thing, too. All these years, man, I still hate church."
