Jesus answered them, “Didn’t I choose you, the twelve,

“and one of you is a devil,” Jn 6:70 WEB

The Greek word used here is diabolos. Its basic meaning is to slander or falsely accuse someone, and is often translated as “devil,” meaning the Satan himself or one of his angels (Mtt 25:41). It comes from the Greek word diabello which has the idea of bringing false charges in order to create a quarrel or a fight.

He is one who has rich gifts from God.

Everything good, everything worthwhile, comes from God, Jas 1:17.

“For who makes you different? And what do you have that you didn’t receive? But if you did receive it, why do you boast as if you had not received it?”
1Cor 4:7 WEB

The Most Holy God made both you and I, but also all the angels, and everything that exists, and Judas Iscariot, and the man of lawlessness. Whatever good that is in him came from God, and whatever good he has also is from God.

In the case of Judas Iscariot he shared in the blessings of Christ with the rest of the apostles. When the apostles were sent on the limited commission Judas was there. When they returned rejoicing that “even the demons are subject to us,” Lk 10:17 WEB, Judas was there. Power to preach, power to heal, daily needs all covered … it was all there.

But a heart prepared with greed.

In whatever combination of circumstances, Judas had a love of money that was part of his undoing. So when some expensive oinment was poured over Jesus feet, Judas asked.

“5 “Why wasn’t this ointment sold for three hundred denarii,a and given to the poor?” 6 Now he said this, not because he cared for the poor, but because he was a thief, and having the money box, used to steal what was put into it.”
Jn 12:5-6 WEB

Characterized by destructive behavior

Oh to have been an actual apostle of Jesus the Christ, to have the opportunity for such a great standing in all eternity. Judas had all of this but was focused on worldly immediate things.

Jesus calls Judas “the son of destruction,” Jn 17:12 WEB, and the man of lawlessness/ the man of sin is also called “the son of destruction,” 2Thes 2:3 WEB (the same Greek word is used in both Scriptures). Both have destructive behavior. They destroy themselves, and bring ruin on many others. If we use Judas as a type of the beast, then there is,

Not quite repentance, but clear remorse, Mtt 27:3.

“4 saying, “I have sinned in that I betrayed innocent blood.” But they said, “What is that to us? You see to it.” 5 He threw down the pieces of silver in the sanctuary, and departed. He went away and hanged himself.”
Mtt 27:4-5 WEB

And eternally cursed.

Terrifying curses are in Psa 69:19-28 of Judas and the others involved. I will only quote a verse.

“Pour out your indignation on them.
Let the fierceness of your anger overtake them”
Psa 69:24

I am inclined to take these verses of the beast also.
