Now, I understand Sid is supposed to be scary he blows up army men with aplomb and creatively turns his toys into hybrid monstrosities. From the perspective of the toys, hes probably the most terrifying thing theyve ever seen. But the fact its from the toys perspective is a very important caveat. In the Toy Story universe, nobody has any idea that toys are technically alive, a rule enthusiastically enforced by the toys themselves. So for humans, the toys for all intents and purposes remain inanimate objects and we can do what we like with them because theyre our property. Remember, this isnt like slavery once again, we have no idea theyre alive, and the toys would rather keep it that way. So when it comes to Sid, one could argue hes just like any kid whos growing out of toys and becoming interested in other things, like DIY and fireworks. Every kid goes through this stage if they get an air rifle, old toys tend to be the targets. Its just a fact of life that working with tools is a healthy interest, and quite a few boys like blowing stuff up. Sid doesnt know hes blowing up living things at all hes simply growing up and becoming interested in other things, like carnage. Whats wrong with that? If responsibly handled, absolutely nothing.
