"If you do what's right, if you live the right way, you'll be taken care of."

Rachel Castillo

What I think this means is that if you do what is right nothing bad will happen to you. For instance if you do bad you will have to worry about the repercussions of those actions. On the contrary if you do good you don't need to worry it's like being taken care of. When you are taken care of that means you have someone will protect you. Now being good is the thing that takes care of you. If you do good what will protect you your actions. Your actions speak and defend you when you are blamed for something you did not nor that you planned to do so.
