No Love Or Hate.

What If ... Love never existed. that it was just made up by someone and decided to make it serious. thought they wouold invent something amazing, if it was made up by someone i would like to meet them and ask them what was going through there heads. If love never existed then i guess, the whole world would be chaos, no human being would judge upon personality or feelings. The world would be shallow i guess. so if love never existed then maybe hate wouldnt either. So when they say 'why is there hate in the world' a good answer would be 'because then there can be love'
Am i right. oh well this is just my ponderings.
but am i right? if there is no love there would be no hate. for hate is the oposite of love?
