>>119928548The murderer book thing is like a Laughing Man meme.
One person goes insane and also becomes obsessed with the book at the same time. He does his crazy thing and kills someone famous. He uses the book partially as an excuse.
Another crazy person tries to emulate the first guy and kills someone famous too for their own insane reasons. He studied the book and had it in his possession, along with dozens of other books.
A third crazy person also had it in their possession and there's no telling how much of the previous two killers he was trying to emulate when he killed his famous target. It had become a meme.
Crazy people read Catcher in the Rye and will use it to justify or guide them in doing something that will ruin their lives.
Even if you claim to be 100% objective, your subjective brain will remind you that there's a >0% chance the book is a CIA brainwashing tool filled with codewords to awaken sleeper agents.
