Oxytocin and morality...

What makes people act with more or less morality? Is there a scientific explanation for it?

Well, at science class I learned that there is a molecule called oxytocin, that is related to the moral of people. These discovery was made by Paul Zak, a brilliant scientific that made a research about morality and how is it attached to oxytocin. These video is really cool and interesting.
