In that sense, I'm not relentless, but perhaps I'm unrelenting. I could relent if I wanted to. But he always has to die. I mean "always" in two senses: at all times and all of the time. I can't kill him all of the time. That would take too long. But all of the times I did, I did. I'd do it again. I could relent if I wanted to, but instead I'd do it again. If he's different, then he's the same and if he's the same, he's got to go. If he were different and not the same, then there would be two things and I'd only have to kill one of them. If only I only had to kill one of him. What a life I would live, if only I only had to kill him the one time. But death doesn't always do him in.
