Did Judas repent?

[TonyChanYT]

Yes according to King James Bible, 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,

Not exactly according to New King James Version

Then Judas, His betrayer, seeing that He had been condemned, was remorseful and brought back the thirty pieces of silver to the chief priests and elders,

he was filled with remorse
μεταμεληθεὶς (metamelētheis)
Verb - Aorist Participle Passive - Nominative Masculine Singular
Strong's 3338: From meta and the middle voice of melo; to care afterwards, i.e. Regret.

The Greek word for repent is μετανοέω (G3340). Judas did not G3340-repent.

Ellicott's Commentary for English Readers:

Repented himself.--The Greek word is not that commonly used for "repentance," as involving a change of mind and heart, but is rather "regret," a simple change of feeling.

Pulpit Commentary:

Repented himself (μεταμεληθείς). This word (differing from μετανοέω, which expresses change of heart) denotes only a change of feeling, a desire that what has been done could be undone; this is not repentance in the Scripture sense; it springs not from love of God, it has not that character which calls for pardon.

At Biblehub, 19 versions use the word "repented"; 20 use "remorse".

Judas was capable of repentance but he did not repent. Instead, he chose to hang himself.
