Do the 6th, 7th, 8th and 9th commandments make up the moral backbone of Christianity?

The second and third tend to be disregarded; also, the third to some degree particularly when we are children. Most of us don't do the first, at least not by physical means. We may badger our relatives to death. Too bad the commandments seem to be negatives. Wouldn't it have been much healthier if we had had more commandments telling positively what we should do, instead of what we shouldn't do?
