The constant psychologizing people do on Elliot and related/similar characters is self-serving and feckless.
<Warning, about to psychologize
It is unsurprising an individual like Elliot percolated from the mire that is contemporary American gender relations. I would argue that while Elliot was a product of his environment (a proto-incel), his mental makeup was what eventually led him to go on a killing spree. Today, many share Elliot's situation, but Elliot was (relatively) unique in that he appears to have been unable or unwilling to question his own views. Rather than pay for a prostitute to break himself out of inceldom or any number of other routes he could have taken, he chose to kill normies. Surely there are many SMV 4-8 incels (well within pre-2014 mating range). I'm sure plenty of these come from upper-middle class families like Elliot's. Why don't these incels kill themselves and/or kill others in greater numbers? They have more self-critical capability than Elliot did. He had very strange behavior which he was unwilling or unable to change.
Much remains to be said about the Beta Uprising, a far more interesting topic than Elliot himself. Love or hate him, Elliot is a part of the "manopshere," a subject that has unfortunately taken a backseat in 2020 along with the Beta Uprising. In fact, the events of 2020 are not disconnected from the Beta Uprising. Using our 20/20 hindsight, we can reclassify Elliot's 2014 Isla Vista killings from a revenge spree shooting primitive insurgent behavior. I would posit that Elliot's subconscious was picking up on emergent phenomena within Western society, and he chose to take action against it. While it is not my intent to lionize Elliot, I would say his killings took a certain amount of bravery, testosterone, and agency. Elliot made a plan and took action. At 22, Elliot was not mentally mature enough to form a detailed plan, and he lashed out at the world around him. A year later, this can be contrasted with Dylan Roof's Charleston Church Shooting where he managed to kill a state senator at only 21 years of age.
It is through this new lens of fourth generation warfare, white insurgency, that we can extrapolate outward toward Brenton Tarrant's Christchurch mosque shootings which ultimately led to the shutdown of 8chan. We are witnessing a growth and progression of ideology within the white incel community. White millennial Americans have been full-spectrum disenfranchised and are in the process of being erased entirely as we head into 2021.
Hopefully I have written enough of interest in this post for someone else to latch onto and run a few more yards with, I am having a rare drink and need a moment to further gather my thoughts on this topic.
