<human>: Hi, I'm watching these "Halloween" films. It's quite clear that this serial killer's primary motive is to prevent any and everyone from getting laid.
Can anyone provide a proper explanation for this?

Now, you can see that he tries to justify these killings by tying the plot in with a single character (usually some bitch/ often Jamie Lee Curtis). But this argument falters once he decides to go kill other teenagers. If you need to kill Curtis, why take these side-trips?

"Oh, I need to kill Jamie Lee Curtis, but let me go kill these innocent teenagers that are in no way hindering my plans. It looks like they're about to get it in."

"Let me wear this mask too because I'm socially anxious and I'll better express myself this way."

Is he pissed that he never got laid before he went all psycho?

Any explanation will be helpful

Could you distill the essence of the text into 1-3 sentences?
<bot>: Myers, there's a goddamn reason that you have like 30 films. Your tactics are inefficient. Kill Jamie Lee Curtis and leave the horny kids alone.
