What did the word HATE come from? what language did the word hate come from? for what the word implies it becomes troubeling for me. What it represents is evil.

From Allexperts.com:
The word 'hate' stems from the Old English word 'hatian' (meaning hatred) which appears before the year 900 AD in Alfred's translation of St. Gregory's Pastoral Care. It's related to the Old Frisian word 'hatia' meaning to despise or hate . Other related words, all meaning hate are the Old Saxon 'haton', the Dutch 'haten', the Old High German 'hazzon', the Old Icelandic 'hata' and the Gothic 'hatjan'. The English word 'hate' meaning despise, appears in the year 1175 and was influenced by the Old English 'hete' meaning hatred or spite.
The word 'hateful' formed from the English word 'hate' appears in about 1380.

Hate is not necessarily a bad word. If you love what's right you're going to hate what's wrong. If you love health you will hate sickness. If you love flowers you will hate weeds. What is wrong is to hate people. The word has been around for thousands of years. Jesus said in Matthew 5:44 "But I say unto you, Love your enemies, bless them that curse you, do good to them that hate you, and pray for them which despitefully use you, and persecute you;"
In my opinion, if you have real love for anything or anybody you will also have real hate for whatever harms that which you love.

Hate, I wanted to know why a person who I do did so much for begun to hate me? BUt when I begun to dig deeper in my understanding it became clear to me. I believe when you admire someone you secretly wish to be or become like person you admire as what you admire is what you want to learn or to have as it feels if we do so then we can be successful or attractive like another. However when failed to become as successful, attractive or powerful like the other you begin to hate this person. Hate is unconscious state of self-denial or self-failure of the person. So there you go by hating someone you hate yourself, all the negative energy directed towards another comes back in worst state to bring you down further. How can you create something beautiful when you think of destroying only? Who does benefit at the end of this mind game? Who is victim here a person who hates or a person who is hated?

Hating is not always a bad thing, as Alvaro points out. I work with children at risk in Indonesia. One thing I HATE are the predators who deal in children. I HATE the abuse that goes on. That is not a bad thing. It doesn't mean I am going to harm the abuser (I leave that to the authorities), but I will stand against the abuse and for the children.
