Note 1 at Mt. 27:3: The placement of Judas' death in chronological sequence could be questioned. Matthew is the only writer to mention it, and he places it in between the religious trial and the civil trial of Jesus. So, Judas could have regretted his actions after he saw that Jesus was condemned by Caiaphas, before He was brought before Pilate.

However, Matthew also mentions Judas coming to the chief priests and elders in the temple and admitting his sin which would suggest that the time was later in the day, after the civil trial of Jesus. Therefore, we have chosen to place Judas' death after the civil trial of Jesus and His final condemnation to death by Pilate so that we can deal with the religious and civil trials of Jesus without interruption.

Note 2 at Mt. 27:3: The Greek word used for "repent" here is "metamellomai" and it is used in the passive voice expressing regret rather than true repentance. Judas regretted that Jesus was condemned (see note 2 at Lk. 22:3, p. 411) but it is certain that this was not the type of repentance that brought him back into right standing with God (see note 2 at Mk. 14:21, p. 420). This is an example of the sorrow of this world that produces death (2 Cor. 7:10)--not the godly sorrow that gives life.
