That’s not what it says. Not a word about tripping or satisfaction, nor is the “reward of iniquity” specified (Judas was a thief and loaded himself up with lots more “rewards of iniquity” out of the disciples’ money bag).
Matthew 27:3 Then Judas, which had betrayed him, when he saw that he was condemned , repented himself , and brought again the thirty pieces of silver to the chief priests and elders,
4 Saying , I have sinned in that I have betrayed the innocent blood. And they said , What is that to us? see thou to that. 5 And he cast down the pieces of silver in the temple, and departed , and went and hanged himself . 6 And the chief priests took the silver pieces, and said , It is not lawful for to put them into the treasury, because it is the price of blood.
Nonetheless, if he hung himself in shame, he couldn’t very well have gone on to buy land with his money. He’d be dead, after all.
