It's a nature/nurture type of distinction when it comes to emotions.
I think INDOCTRINATION can produce certain learned emotions. That is why there are exit counselors. For some people exiting a cult is a difficult process. They need to get rid of cult learned values and behavior as well as the emotions tied to the indoctrinations they were subjected to over the course of many years.
Nature on the other hand, provides a vast range of emotions. Some are critical to our survival, like tetra pointed out.
If men and women were not biologically attracted to each other and ACTED on this attraction, the human species would cease to exist. If this natural attraction between the sexes were not controlled, there would not be anyone "tempted" to cheat on their spouse who could successfully fight off such temptation.
Most parents act to protect their young when these face eminent danger. There is such thing as natural affection. If this were not the case, we would see abandoned children everywhere. Thankfully the majority of parents love their children.
