Aule as a troublesome vala

[Son of Fire]

Aule seems to have a most terrible track record, he made the dwarves before it was time to have the children of lluvatar around, he was the vala over both sauron and sauremon before they fell, and he was the mentor of feanor. The real question is, was aule just unlucky, o was Tolkien trying to make a point. I was reading thet he hated industrialization, and was an avid naturalist, so that would perhaps say that he wanted to show that those who try to invent only cause more prolems, but maybe he just needed a vala from which all of these bad(okay, definitely not the dwarves, but the fact that he made them of his own accord, without asking eru lluvatar first was bad) things would come. I believe it was a subtle hint that inustrialization causes more problems than the good it provides, but what do you think?
