How do you think each type can destroy themselves?
My theory is that by opening up the 4th function to others, this can be harmful. Also hidden agenda related stuff although that is usually excused by society, unless extreme.
Foe example, and ENTP might go down by opening up to strangers and then being hurt by it, thus hardening their hearts making them even less trusting of others. They may also become too posessive and controlling with their own friends especially the old ones who they begin to take for granted. This may cause them to loose their friends and become less loved. So it seems the hidden agenda is something you do to test the boundaries and then end up with less, and the POLR can cause you to want to open up your most vulnerable areas to someone, which can be deadly as well. Can anyone think of other ways a type can bring themselves to a sudden end?
