mp,
Keep in mind that everything Hashem commanded us is the best thing for us AND for the whole world. Meaning by following His laws we are creating a perfect world and if we dont we are destroying it. (And its not just because one is a mitzvah and the other is an averah.) Hashem gave us those mitzvah and those averahs because these set of rules is exactly what is required for the world to exist. We are the first beneficiary of our deeds because we are closest to it then our families, our city, our country and the whole world gets affected by it.
