I'm not completely convinced of that but, at any rate, Judas is an example of worldly sorrow that leads to death while Peter is an example of godly sorrow that leads to repentance.
Okay, then how is Judas' repentance about being instrumental in the crucifixion of Jesus different from others' repentance about being instrumental in the crucifixion of Jesus? You're saying Judas' sorrow led to death, but why did others' sorrow over the same thing lead to life?
Judas repents:
Matthew 27
3When Judas, who had betrayed him, saw that Jesus was condemned, he
was seized with remorse and r
eturned the thirty pieces of silver to the chief priests and the elders.
4“
I have sinned,” he said, “for I have betrayed innocent blood.”
These other people repent:
Acts 2
36“Therefore let all Israel be assured of this: God has made this
Jesus,
whom you crucified, both Lord and Messiah.”
37When the people heard this,
they were cut to the heart and said to Peter and the other apostles, “Brothers,
what shall we do?”
38Peter replied, “
Repent and be baptized, every one of you, in the name of Jesus Christ
for the forgiveness of your sins. And you will receive the gift of the Holy Spirit.
