<< Why are we even worrying about those? Those laws are Old Testament and don't apply anymore. Read Matthew 5, 6, and 7 for the new covenant that Christ set in place after fulfilling the first. Then ask yourself how many of those you've broken.

You're thinking of the Old Covenant. The Old Covenant is about how to be saved from you sins (since Jesus didn't die for us yet we couldn't be saved through Him) and also the Laws of Moses (laws about how to grow your beard, eating certain food, etc).
Since the Ten Commandments were written by God and were a law that would be with Israel (God's true church) they still apply to us now. Jesus touched upon each and every law in the Commandments and did not state that they are no longer in effect.
That's just scratching the surface....there have been huge studies done on this.
