God and Christians do hate the wicked but only after the wicked clearly side with the devil against God after having been exposed to God's truth and love in trying to get them to turn from their sins and seek God's forgiveness for those sins.
Psalm 5:5
The foolish shall not stand in thy sight: thou hatest all workers of iniquity.
Psalm 11:5
The Lord trieth the righteous: but the wicked and him that loveth violence his soul hateth.
Psalm 26:5
I have hated the congregation of evil doers; and will not sit with the wicked.
Psalm 31:6
I have hated them that regard lying vanities: but I trust in the Lord.
Psalm 139:21-22
King James Version
21 Do not I hate them, O Lord, that hate thee? and am not I grieved with those that rise up against thee?
22 I hate them with perfect hatred: I count them mine enemies.
