If you think about it, while {-Ha'} can mean both "undo" and "do wrongly", it doesn't really make sense for it to be possible to have both meanings on the same verb. If it did, then how would I know if you meant "be unmotivated" or "be wrongly motivated" (be motivated but in a bad way, or for the wrong reason)? How would I say that the judge has commuted ({wuqHa'}) my sentence, rather than that he had wrongly decided upon my sentence (a rather important legal distinction)? Of course, language *can* be ambiguous, but in this case, I think the dozens of examples from canon strongly suggests a pattern. I think this is one of those cases where TKD offers a bare sketch, but we actually have a lot of canon examples to justifiably derive something which is almost a rule.
