He lost all care and destroyed himself in whatever means he could think to join Satan.
I really don't believe that Judas intended to join Satan.
"Companions and Competitors," Meier notes that there are only two basic things known about Judas: Jesus chose him as one of the twelve apostles, and he handed Jesus over to the Jewish authorities.
"These two bare facts are almost all we know about the historical Judas. Beyond them lies theological speculation or novel writing, with the dividing line with the two activities not always clear-cut."
This is not too far off from your previous post
Remember that we do not have accounts that Judas was a witness when Jesus was questioned, suggesting that Judas wasn't denying that Christ was the Son of God, but instead he felt like He could manipulate the time of His power by offering the Jews a way to obtain Jesus.
One Scripture scholar, the late William Barclay, professor of divinity at Glasgow University, and author of the widely used multivolume Daily Study Bible, suggested that the most compelling explanation is that in handing Jesus over to the Romans, Judas was trying to force Jesus's hand, to get him to act in a decisive way. Perhaps, he suggests, Judas expected the arrest would prompt Jesus to reveal himself as the long-awaited Messiah by overthrowing the Roman occupiers. Barclay noted that none of the other traditional explanations (for example, greed, disillusionment, jealousy) explain why Judas would have been so shattered after the crucifixion that he committed suicide. In other words, only if Judas had expected a measure of good to come from his actions would suicide make any sense.
