Furthermore, the mere existence of bad articles encourages more bad articles to be added. Incomplete is one thing - that is relatively easy to fix - but bad is another and if often much more difficult to fix.
I agree. But if the topic is _itself_ valid, then the right thing to do with a bad article is to fix it, not delete it or redirect it. It's usually pretty easy to go to an article, and move the bad parts to the talk page along with a courteous request for more documentation, or rewriting of some biased terminology or whatever.
