Good one Mastodon, if that picture only had sound effects.
As to whether there is any good in the JWs, most other religions or the Bible(s) my response is this. Imagine a gourmet meal cooked by one of the best chefs in the world. Now imagine him pouring some sauce made out of excrement over his dish and serving it to his guests. What do you do? Try to take the "good" with the evil? Try to rinse off the excrement from the rest of the plate in order to salvage whatever is "good" or better yet throw the plate in his face?
Whatever good there is was has been contaminated beyond repair. Therefore the short answer to the question is, so what if there may be some good (in an abstract, intellectual way) in the religion if you end up hugging the toilet after partaking of their spiritual meal.
