My take is that it starts out by using the "find the difference" to imply there is the possibility that one image is better or worse than the other. Both images are the same, with no punchline or hidden joke.

Naturally, the reader looks at the bottom for the answer to the puzzle. The answer key then calls you out as the bad person for looking at the answer and cheating. The comic calls you evil, but meanwhile, the person in the comic is pouring acid on baby animals.

This could be it. I didn't think of the cheating aspect of going straight to the answer. If this was the intent, I think he should have added "CHEATER!!!" in the answer to let us know why we're such terrible people.
