Jesus hated his enemies because Jesus was righteous and the righteous do that too.

Jesus hated his enemies. Jesus also hated the wicked, just as Yahweh his God does.
If Jesus was righteous, then Jesus also hated:
Proverbs 29:27 The righteous hate the wicked, and the wicked hate the righteous.
Jesus hated his enemies because Jesus was righteous and the righteous do that too.
The wicked were Jesus’ enemies, therefore Jesus did not practice love for enemies, nor did he even preach it, love for enemies is the phrase of Cleobulus of Lindos, a Greek who lived in the 6th century BC, the Romans took his phrase and put it in the Bible. That is why on his return he says to the religious Roman preachers of a false gospel in the Bible: I have nothing to do with you hypocrites, you have not preached my religion but the religion of Rome:
Matthew 7:23 And then I will declare to them: I never knew you; Depart from me, you workers of iniquity.
Psalm 139:19 Surely, O God, you will put to death the wicked;
Depart from me, you bloodthirsty men.
20 For they speak blasphemies against you; Your enemies take your name in vain. Do I not hate those who hate you, O Yahweh,
And am I not angry with your enemies?
22 I hate them completely;
I regard them as enemies.
