The following is an excerpt from Jimmy Akin’s book A Daily Defense regarding Judas’ death:
Judas probably began accompanying Jesus while in his twenties (Jesus himself began his ministry when about thirty; Luke 3:23). This suggests Judas died a sudden and remarkable death (i.e., not an ordinary death due to old age). Matthew’s report of his suicidal hanging accounts for this, leaving us to explain Luke’s reference to him falling and bursting open.
The earliest explanation is found in the second-century historian Papias, who wrote around A.D. 120. His works are lost but partially preserved in other writers. According to the fourth-century writer Apollinarius of Laodicea, Judas survived the hanging by being cut down before he choked to death, but he quotes Papias as saying Judas suffered severe swelling (edema) of the head and body, eventually causing him to burst open (see Monte Shanks, Papias and the New Testament, chapter 4, fragment 6). We now know that edema of the neck and body can be a consequence of strangulation, so Papias’s account may be based in fact.
Now this seems to open the possibility that Judas attempted to hang himself, yet the rope slipped, and he later died of an edema. If this is how it went down, it’s possible that Judas realized he was wrong and repented, but died afterward from the edema.
We can look to Matthew 26:24 which indicates that Judas’ story does not end well, to say the least. So what is everyone’s opinion on this? Is there any evidence to suggest that Judas is indeed in Hell?
