"And that's what I liked about it, because they are, in the beginning, your little beautiful stock figures, who then make a decision to preserve their futures, but the decision they make isn't completely right, and it destroys their futures"

This quote speaks with the idea of making choices that have unintentional repercussions. The "little lovely stock figures" are most likely characters in a story, and the decision they make is one that is implied to maintain their futures, but instead it winds up damaging them. This speaks to the concept that even when we make choices with the best of intentions, the result may not be what we anticipated. It is a reminder that we ought to bear in mind the choices we make and the possible effects that might occur from them. It also speaks with the idea that life is unforeseeable and that we need to be prepared for the unanticipated.
