A very inconvenient truth which the bible teaches and which JWs try to hide from is that God does foreordain people to do evil deeds!
Note what the bible really teaches:
(Acts 4:27, 28) . . .Even so, both Herod and Pontius Pilate with [men of] nations and with peoples of Israel were in actuality gathered together in this city against your holy servant Jesus, whom you anointed, 28 in order to do what things your hand and counsel had foreordained to occur.
(Acts 2:23) . . .this [man], as one delivered up by the determined counsel and foreknowledge of God, YOU fastened to a stake by the hand of lawless men and did away with.
JWs are in denial of the true harsh character of the God of the bible. They even deny that he is vengeful despite the existence of texts like these:
(Psalm 18:47) . . .The [true] God is the Giver of acts of vengeance to me; And he subdues the peoples under me. . .
(Psalm 58:10) . . .The righteous one will rejoice because he has beheld the vengeance. His steps he will bathe in the blood of the wicked one.
(Psalm 94:1, 2) . . .O God of acts of vengeance, Jehovah, O God of acts of vengeance, beam forth! 2 Raise yourself up, O Judge of the earth. Bring back a retribution upon the haughty ones.
(Isaiah 47:3) . . .You ought to uncover your nakedness. Also, your reproach ought to be seen. Vengeance is what I shall take, and I shall not meet any man [kindly].
(Zephaniah 1:17) . . .And I will cause distress to mankind, and they will certainly walk like blind men; because it is against Jehovah that they have sinned. And their blood will actually be poured out like dust, and their bowels like the dung.
(Revelation 18:6) . . .Render to her even as she herself rendered, and do to her twice as much, yes, twice the number of the things she did; in the cup in which she put a mixture put twice as much of the mixture for her.
Now compare the above texts and Psalm 109:6-19 with this standard definition of the word vengeful:
vengeĀ·ful
[ venj -f uh 
l ]

So Jehovah is not a vengeful God, huh JWs?
