After a short study on the "hateful" words of Jesus it seems that when Jesus spoke of hate, it was hatred of evil. As the Greek definitions convey the word hate when used as a noun or adjective has very strong implications. I found no evidence of Jesus using hateful words as talked about in some posts below. Scripture references are from the New International Version
