Narcissists (or those with insolent pride, see here), frequently “use” others as tools to achieve their goals. Once the narcissists have gotten what they want, they easily discard the people they used without any further consideration. An example is how the narcissistic Pharisees (see here and here) treated Judas after Judas had betrayed Jesus.
Now when morning came, all the chief priests and the elders of the people conferred together against Jesus to put Him to death; 2 and they bound Him, and led Him away and delivered Him to Pilate the governor.
3 Then when Judas, who had betrayed Him, saw that He [Jesus] had been condemned, he [Judas] felt remorse and returned the thirty pieces of silver to the chief priests and elders, 4 saying, “I have sinned by betraying innocent blood.” But they said, “What is that to us? See to that yourself!”5 And he threw the pieces of silver into the temple sanctuary and departed; and he went away and hanged himself.
6 The chief priests took the pieces of silver and said, “It is not lawful to put them into the temple treasury, since it is the price of blood.” 7 And they conferred together and with the money bought the Potter’s Field as a burial place for strangers. 8 For this reason that field has been called the Field of Blood to this day.9 Then that which was spoken through Jeremiah the prophet was fulfilled: “And they took the thirty pieces of silver, the price of the one whose price had been set by the sons of Israel; 10 and they gave them for the Potter’s Field, as the Lord directed me.”
In this case, after the Pharisees (chief priests and elders) were more than happy to use Judas as a tool to get what they wanted (the destruction of Jesus), they did not care the slightest about what happened to Judas. He was just someone to be used as means to their end. This is consistent with insolent pride – looking down on others as of much less importance, and therefore merely to be used and then easily discarded with no further consideration of their needs.
This principle has a second application in this case. Judas was not only a tool of the Pharisees, but was also a tool of Satan in Satan’s quest to destroy Jesus. Satan (a “narcissist” filled with insolent pride, see here) also uses people for his evil purposes, and then drives them to their destruction.
