Well, with most of the major league baseball players fighting overseas, pushing cripples in front of trains was one of the only sports the people on the home front really had left.
Seriously, though, while I certainly support the handicapped community, I don't think pushing a double amputee in front of a train is necessarily worse than, say, feeding a live woman to caged rats:
Actually the amputee is fleeing. He's the bad guy in the story.
Hmm. I don't think so, though there are two amputees in this story, so it's a little hard to say. But since the first amputee gets shoved in front of a train at the beginning of the story, I assumed that was the scene being depicted on the cover. The second amputee is the guy that dies by being tossed around the room like a football.
Or maybe this is just a third hard luck amputee!
I think you're right. I never thought the cover depicted this as a murder. I always looked at it as the amputee is trying to escape or he's committing suicide. But now see your interpretation makes more sense.
