Tell me what motivates NAME_1. What does he want in the end. What is his long term goal:
Setting: A prestigious boarding school for gifted students, where the main character is a charismatic and popular senior who excels in academics, sports and arts. He is also secretly a sociopath who has killed people.

Conflict: The progonist has a twisted obsession with death and killing. He believes that he is superior to everyone else and that he has the right to decide who lives and who dies. He has powers granted to him by a knife which in exchange he has to kill. The more he kills the stronger the powers become and if he doesn't kill, the powers become weaker. He found the knife along with a note with instructions about this arrangement. He has killed several people, mostly strangers, and has never been caught. His life is disturbed by a detective who poses as a history teacher because he thinks the murder is in the school since the first two killings were from that school and were messy as if the killer was still learning.
