Exactly. Is it so important whether it was the mob, a street mugger, some teen gang or the power rangers? No.
And clearly he seems like a tormented man by the "stranger" line. So i think that him inflicting it on himself one way or the other is far fetched. The Shape came with the 50-50 idea, which frankly is based on nothing besides his fiction (no offense) and now only sees it. I could equally argue about another far fetched idea and defend it thoughout this thread.
Point is, as Nepenthes says, lets keep it simple. Some dude/gang whatever tortured this man. End of story. Imagining Darkseid coming down on earth and doing it isnt necessary nor does it enhance the experience.
