To answer this first question, I look at the philosopher Satre and his idea of ​​existentialism. With the belief that people do not have a predetermined nature or essence that controls who we are, what we do, or what is of value to us. People are then radically free to act independently of the determination of external influences. By living with indifference, we are then able to create our own nature or, in the case of the quote, create our own happiness through our family, our friends and our work to improve the future. As humans and having the choice to do what we want, we are always responsible for our actions and their consequences, which leads us to believe that every event has a particular cause. The reason for this cause and consequence could be seen as a kind of moral behavior.
