Hate and Love?

The saying "destroy what destroys you" - some might see the saying as a show of strenght, others might find it as their help to suicide. But if we have to destroy what destroys us, why is it illigal for me to destroy a person that destroyed me? If I was allowed to kill the person I truely hate, I wouldn't, I would want her to suffer, to feel pain and make her regret what she did. But then she would be allowed to do the same back at me. So I guess I wont get to see her in pain... Maybe one day, but not because of me.

 Well maybe.. I know... Next time she talks to me, I will speak from my heart... The real me. All the stuff I have had in my mind since she came along. I trusted her, and she threw me on the ground so hard and so many times it's too hard for me to get back up again. 

I have never really believed in the word hate. It has been so over used, just like love. The word isn't that special any more. So what do we do when we more than the expression hate a person, and more than the expression love a person? What are the new words for hate and love?
