"I am not bound to win, but i am bound to be true. I must stand with anybody that stands right, and stand with him while he is right and part with him when he goes wrong." 

-Abraham Lincoln 

We wont always win but that's okay. All that really matters is that you are true and that you choose the right. Choosing the right would be failing a test because you didn't study, not cheating on it. You should always choose the right and you should encourage others to do so. You shouldn't stand by people who do otherwise, they will go down and take you with them. You want to set a fine reputation for yourself and be very successful. Don't let others take that away from you, dont ruin it with you r bad decisions. If you know its wrong, don't do it. It can lead to many repercussions. Its all up to you.
