He created them. If I create a thing out of clay, I can pretty much do whatever I want with it. If a bowl leaks, I can throw it away if I so choose. Heck, even if it is a GREAT bowl I could throw it away. Good thing I'm not God. ;)

That's a ridiculous analogy. Of course you can do what you want with a piece of clay, but it is a different thing entirely to bring harm on a conscious being.
