Seriously no diplomats?)
You don't negotiate with insects.
That said I'm with Reelya here, it is kinda strange viewed in a modern day view, though of course you also need to remember that Superman was first written in the early 1930's, which put it simultaneously still just a little bit before the golden age of science fiction started (late 1930's) and still 20 or so years before our first ever actual scientific exploration to space (as opposed to the german missiles of war). It's important to remember that at this point just the idea of "he came from another world" was still a pretty revolutionary one in america, and the idea of another planet actually being sensible on it's own (instead of just being a caricature of earth) was still one that had yet to be really developed.
Heck even modern days the (WARNING)
Planet of Hats trope is still rather common, so I'm not exactly surprised if canon of something that was written 80 years ago pulls on that trope a bit. Because over the years of superhero stuff we've determined at least one solid point, you don't mess with the key points of a superheroes backstory. You can bend things all you want and fiddle with the details, but Krypton has still got to explode with all souls aboard, and Mary Jane has still got to die. To do so otherwise is to invite fan backlash similar to what we saw with the more recent fantastic four film (which had plenty of other problems, but there was still plenty of backlash on the interwebs as well). And when you are trying to make money, well, backlash isn't necessarily a thing you want to be having.
Edit: AAAAHHHHH! I've been surrounded by ninjas!
