Hatred is part of humans emotions, sometimes it take away the better part of human, it prevents some people from liking/loving and caring for one another, it is a strong feeling of dislike, disgust, bitterness, irritation, enmity, Hostility and anger towards someone/something or group of people.
Some people will hate you for no reason, as long as you don't depend on them financially, just ignore them and you will keep shining, don't force yourself to anybody by trying to impress them and don't please anyone, because no matter what you do will never be enough for them, just live your life as you please.
But sometimes it's really difficult to identify who your real enemies are, some friends are bad friends they just pretend to be good, they are the dangerous snakes around you, so be careful how you exposed yourself to peoples.
If you distance yourself from your enemies by 1 kilometer, then distance yourself from your friends by 100 kilometers, because they know you in and out, and it will be very easy for them to harm you. Wise man says "keep your friends close but your enemies closer", because one day your friends may become your enemy and your enemy will become your friend, but doesn't mean that all friends are bad. Things that causes hatred are: pain, misunderstanding, injustice, jealousy, fear, envy, frustration and so on. May the hatred in our enemies hearts turn to love.
