when you have suffered and been held in misery terrible at the hands of other people,hate is something that develops in the persons heart.when you experience something like that only then will you learn how hate cannot be ignored and its not an emotion that can be suppressed easily.i have been through this,and maybe unintentionally or delibrately,i cant let go of hate ,because maybe thats what helps me face the person and bear the pain,and once it is gone,i wil be forced to deal with pain.
If you dont know hate,you dont know to what depth you can love,what love is.when you've been through hate,you love your loved ones even more.
Hate is a completely natural feeling,and it can stay even when you have forgiven the person,because then you dont want anything to do or to say to them.
Hate may subside and eventually die because time takes away pain,but not for all.and the least you could say when you hate is,if you dont hate them you dont love them either.
