[Hebrews 11:6]

Judas is alone, filled with remorse, dejected, tormented by his evil action

As the monumental nature of his betrayal dawned on him, he could not process it.

[Scott from the Left Coast]

I don’t think it is humanly possible to process that level of self-horror. To grasp what he had done clearly and to to have full knowledge of what he had done…for all time and beyond time…that was his curse, as he died by his own hand the full weight of his actions was present within him.

The great irony for him is that death was no release at all for him, as the Christ showed just three days later. His desolation is eternal.

[etabeta]

Yes, he felt remorse but it seems he never asked for God’s forgiveness.

[spankalib]

Make friends with the hangman so he ties and places the noose properly; so at the end of the drop, the tooth-like dens of C2 (the 'odontoid' process) slams against the midbrain/pons/medulla - killing you instantly.

I suspect Judas did (k)not know how to tie & place the noose correctly, thus strangled & involuntarily kicked & struggled, thus breaking the rope...

He was remorseful though, so it is sad all around, to me, that he killed himself instead of asking for forgiveness.

Regret would be concerned about the consequences of your actions to yourself.

Remorse would be concerned about the consequences of your actions to others.
