Why does love exist?
Love is just part of human nature as well as many other emotions. It is very complex and can result in many good occurrences in human history as well as bad occurrences. To many, it does not have any particular purpose on it's own as to why it exists but to exist because of how we are. With that said, many believe that we, ourselves, can give love a purpose with the ultimate goal being nothing but pleasant toward humankind and the the entire world. (e.g. peace, compassion, health, etc.)
