I think that not completely understanding why he kills makes him that much scarier. He kills because…well…he just kills. He is a killing machine. And, you can’t kill him. And he doesn’t stop…Happy Halloween!
Regardless of which of the Halloween film- original or reboot- you quote from they both agree that he became a murderer when he killed his older sister and was Halloween Kills institutionalised as a consequence so my opinion is that he just developed a macabre taste for murder and had a specific victim type and he only killed the teen boyfriends and any other males as they were in the way
because he hates everyone and he is to weak to bring himself out of the darkness if he would he would probaly be a person who doesent now anything and he would be stupid and be like who am i and they would say u were micheal myrers and u killed about 100 people every halloween
