Here's another one that I just found thanks to Snarky the Apologists on Youtube:
1961 WT 7/15 pg 420:
Jesus encouraged his followers to love their enemies, but God’s Word also says to “hate what is bad.” When a person persists in a way of badness after knowing what is right, when the bad becomes so ingrained that it is an inseparable part of his make-up, then in order to hate what is bad a Christian must hate the person with whom the badness is inseparably linked. Indicating that Jesus did not mean for us to love the hardened enemies of Jehovah, David expressed this God-approved attitude: “Do I not hate those who are intensely hating you, O Jehovah, and do I not feel a loathing for those revolting against you? With a complete hatred I do hate them. They have become to me real enemies.”—Matt. 5:44; Amos 5:15; Ps. 139:21, 22.
