There is no doubt that God hates the sinner (Psalm 5:5; Lev. 20:23; Prov. 6:16-19; Hos. 9:15), of course Satan is chief amongst them. The question is do we have the right to make judgement of the sinner or are we limited to judging the sin.
Matthew 5:44 "But I say to you, love your enemies and pray for those who persecute you, 45 so that you may be sons of your Father who is in heaven; for He causes His sun to rise on the evil and the good, and sends rain on the righteous and the unrighteous.
I can hate Satan's work and stand to fight against him, but do I have the right to hate a creation of God? This kind of hate is a judgement that I am empowerd to make?
Proverbs 8:13 "The fear of the LORD is to hate evil; Pride and arrogance and the evil way And the perverted mouth, I hate.
Psalm 97:10 Hate evil, you who love the LORD, Who preserves the souls of His godly ones; He delivers them from the hand of the wicked.
