I also wouldn't really be surprised if it turned out that what the deva had been about to say was, "I don't see any significant evil...but I also don't see any significant good. You spent part of your life adventuring, but because it was what you thought a wizard should do, not because you cared all that much about making the world a better place; you spent a while hunting a horrifyingly evil sorcerer, but only because one of his victims happened to be someone you cared about personally. In your personal life and in your marriage, this pattern continued: you fulfilled bare-minimum standards as you understood them, and didn't bother to try for more. Looks like it's Mechanus for you."
