I don't think the last part of the song is actually about the crucifixtion of Jesus. I think he was using that as a metaphor and an analogy. I'm not sure exactly what it is, but I'm supposing that it's about a guy loves a girl, but she doesn't share his feelings and he wasts a lot of time over her, which is bad because she's really bad for him. The final part suggests that he feels that he's suffered greatly because of her, as if she's crucified him, and he's basically a goner. Usually I'm better at wording this stuff, but for some reason I can't right now.
