What is it really?

Love is the emotion a majority of us wish to have, it's something that fulfils our life. Whereas hate is a strong emotion for someone you dont like, someone wwho has wronged you, someone who you can not stand to be with. So how can you camoflage to passionaite emotions into one. Love is beauty it is life where as hate is dispair so I don't think its a camouflage for love maybe foor something else, I mean what is it really?
