The Ten Commandments are not the moral law. They were a law for Hebrews at Sinai and in Israel. The moral law is the commandments of Jesus, and they are different.
Also, this whole business of "the moral law" is NOT PART OF THE LAW. The ceremonial/moral distinction is not in the law. It's made up. And making things up is adding something, and that's breaking the law.
Really, you are in a trap. You need to stop studying Moses and focus like a laser beam on JESUS. HE is the one God told you to listen to.
Jesus gives a different set of laws that will get you damned. They're in Genesis, and they're not the ten. Theft and covetousness, for example, are not on the list of things that will get you damned to the lake of fire - not there. Property crime and thought crime about property are part of the Ten Commandments, but NOT part of Jesus' list of deadly sins.
Really, you will do so much better if you devote your energy to understanding JESUS' law fully. It is much more complex and much harder than Moses'. You can't keep it either, but Jesus never said "break one, break 'em all". Rather, he said that to be forgiven by God, you have to forgive. It's a very different law.
