Never should we hate anyone, and I will explain the reason to you. Hating someone, you have to go employ the dark sides of human nature to do bad things to him or her. Doing so will cause you to fall into an abyss of evilness. Never go hate anyone since hatred will make you do a lot of bad things (physically or mentally) against such a person you hate, and gradually you will lose your conscience and kind heart required to be a good person.

The worst is you would go on denying the dark sides of human nature insisting that what you have done bad is right and proper. Not until one day you find the one you hate most is yourself because you have discovered that you have become an evil person do you know what hatred literally tells us is we should better love each other.
