We choose who we want to be. Our path is undefined. All those mistakes that we make, we have no excuse for them. All those good memories are the same case. Sure you can be influenced, but ultimately you are the holder of your destiny. You control your happiness. You control your sorrow. You control your anger. You control your reactions. Other outside sources may hinder your ability to control, but YOU are in control. Don't blame Johnny for breaking your heart. He screwed you over, but you have control on how long you're going to sit around in your pajamas, eating Ben and Jerry's, crying over him, or getting out there and moving on. Don't blame Susie for bringing up a controversial topic. You could just as easily changed the subject.
At the same time, be careful of your actions. Other control their destiny just as much as you control yours, but if you understand how hard it is to overcome outside influences, why would you wish that on anyone? Be careful how your actions will influence others, because they will. Susie brought up that subject, because you commented on something related. Johnny stood you up, because you freaked him out with all the calling. We live in one big circle of actions and consequences.
But just because you now understand that EVERYTHING you do effects someone else, don't act accordingly. Be yourself, but be a good person. Don't hate. Don't discriminate. Don't judge. Don't use violence. Try loving, caring, being compassionate, and patient. Look at how you are being effected by others bad decisions, and look farther down the circle. Are you the true cause? Then you can be the solution.
You control your destiny. You control what happens to you. All through other people. Why would you wish harm on yourself?
