My point is, I think Spidey's origin was very advanced for the time. It was the comic with the best message. Its just one of those stories that you could set in about any universe and it would make sense. And since you like to be a smart-ass, I'm not saying radioactive spiders biting teenagers who then devote their lives to fighting crime could fit into any universe, I just mean the core elements of the story stand the test of time. Sandman being Ben's killer wouldn't change the fact that Peter learns his lesson, it would just take away from the story in my opinion. Its a classic story that, in my opinion, doesn't need to be altered.
