Oooo... trick question. Logically, loving would make one a better person. When we love it gives us a feeling of satisfaction; sometimes pleasure (even when we show love to a complete stranger). However...
We are designed to both love and be loved. If any of these are missing in our life, we feel incomplete. Not being loved can cause a person to become despondent, lonely, depressed. Not giving love cases one to turn inward to themselves (self love). They become egotistical and narcissistic. This makes it hard for them to be loved by others. They end up empty inside.
Being loved and giving love are intertwined. Ideally, one works off the other. When one shows love, they are more apt to receive love. When one receives love, they are more apt to show love.
