Law, or self contentment?

A guy is driving down the road, it's long and straight...it's alright to go over the speed limit because he couldn't hurt anyone...right? He goes faster, faster, and faster...that rush of speed is just amazing! He's totally caught up in the moment, then all of the sudden, he's gone further down the road than he'd planned, and a car is pulling out...he hits it. The person in the other car dies, he lives with injuries...but he now has the blood of another person on his hands. Was speeding worth it? His idea: that speeding was alright. Yet, he killed someone from his belief, instead of what the law said. There are a lot of laws...all given for our safety. Laws of man, and laws of God. Laws of man, sadly, are kept a lot more than the laws of God, even though they're all written on our hearts. Everyone knows that stealing, killing, and lying are wrong. While people do have to make their own decisions and find out what they believe, there are laws that tell us what's right and what's wrong. A lot of people seem to do things simply because everyone else is doing them. After that we say, "everyone is doing it, so it's normal" which makes it accepted by most people. If you don't "go with the flow" then you're considered an outcast. What is it that Christ told us? We're not to fit in with this world. If we didn't stand out, people wouldn't come and ask us what we have that makes us so different.
