“Right is right, even if everyone is against it; and wrong is wrong, even if everyone is for it.”

This quote implys that you need to do the right thing even if everyone else is against it. You need to do what you think and feel is right and best. What everyone does shouldn't affect you. For example if the whole school was against using uniform but it's a rule then you need to follow the rule regardless. And if someone is doing something wrong for example drugs then you shouldn't give in even if everyone else has or feels like it's the best thing to do. So if you are doing something that is for the best then don't feel bad or pressured by others to do otherwise.
