Who is the person you hate most?

Hatred is the most awful feeling within humanity but the reasons can make it valid or invalid some people hate others due to jalousy and some for there personal reason when they are not getting response or respect these are some common problems which can be forgotten as the time goes by .......... but when the hatred comes on the basis of masses like racism on the basis of culture,language & color of the skins it is ultimately harmful and cannot be forgotten easily because this kind of hatred can cause so much destruction and devastation among humanity ...... So my religion Islam says do not hate the man but hate his deeds and wait for his consciousness which he may lost because of his pride,lust or for any other reason but after long time when you find him bad to the bone then punish him so he will never be fine and will cause a major effects within your society and will harm other people ......... So i think hatred for personal reasons and cultural reasons is not valid but hatred for a persons deeds is valid but even we should not loose our petience to wait for his righteousness to come back .....
