"If your so called friends urge you to do anything you know to be wrong you be the one to make a stand for even if you stand alone have the moral courage to be a light for others to follow

 I think it means that in the end you truly by your self. And that whatever people say you dont have to obey them. If they tell you to do something you dont like dont do it say im a ctr person and i obey whats right. If they say your dumb  repeat it again. For example if they bully a little kid you say stop you violated the ctr rules and tell the teacher on them because thats doing the right be a ctr person.
If you be a ctr person good stuff will come to you and you will be guaranteed a good feeling after you choose the right --------> Even if you look dumb or you loose your friend along as you choose the right and you could go make better friends then those meanie ones. If a kid does something bad like breaking the law you go snitch on them even if they dont like it your choosing the right thats all that matters. You might loose friends but as long as your choosing the right then your ctr.
