@FOUND SOUL,
Foundy, I really think his story is that of someone who always felt socially marginalized and socially inadequate, not fully accepted into any peer group--he tells us that was the case even in pre-school when he pretended to be some sort of assistant goalie, because he couldn't play football, or even understand the game, as well as the other boys--he was pretending, even at the age of 5, to try to cover up his feelings of inadequacy.
Then he immigrated to another country, and he was anxious to acquire an American accent, because he didn't want to seem different. Then he wanted to be a blonde, something most Asians, or bi-racial Asians, are not, so this may have been an attempt to be seen as more Caucasian. Again, I can see these things as early attempts to deal with his own feelings of inadequacy, that also involve some degree of pretense in his case. And they are identity issues.
As he moved into Middle School, he couldn't compete with peers, not just with the cool kids, in terms of simply having friends and some sort of social life, so he retreated into the game World of Warcraft which gave him an alternate reality that was "more fair" to him, he could compete and participate in it on an equal level, and have something to discuss and share with others involved in WOW. But, eventually, he felt the discussions by other players were dominated by "normal" people, and it was too much like the real world, so it was no longer a place of refuge, and he abandoned it.
By the time he was in high school, he couldn't cope with any sort of perceived competition with other boys, not even at an all-boys school, where the presence of females was not an issue. And, when moved to a coed school, he began to really be obsessed with not being able to attract girls, or to even be noticed by them. This then became a serious identity issue for him--as a male--and working out identity issues is one of the main psychosocial tasks of adolescence. He tried to compensate by seeing the successful boys, mostly the jocks, as "brutes" while he saw himself as superior intellectually, but he wasn't having any real academic or intellectual successes either, so his alleged/fantasized superiority in that area didn't give him any satisfaction or social boost either, it was just something in his own mind he tried to comfort himself with.
His grandiosity/feelings of superiority, in response to his being a social loser, and misfit, wasn't effective as either compensation or psychological defense, and I think, by the time he got out of high school, he knew his future as an adult--in all areas of life--was likely not to be successful by his standards--and he'd never achieve the status and recognition in life he felt he deserved in all areas. By this point, his thinking was already clearly disturbed, he was obsessively focused, to a pathological degree, on only one thing, and his obsessions made it impossible for him to function in a college classroom or to complete courses, and he dropped out of the two colleges he tried to attend on a part-time basis.
At that point, his mother got him a job coach--she obviously wanted him to have some kind of independent life in adulthood, particularly since getting a college degree seemed unlikely, so he'd need to get a job. He rejected everything the job coach came up with--menial work was "beneath" him, he'd be "mortified" to work in "retail", etc. His snobbery, and self-delusion/grandiosity, further prevented him from being able to deal with reality, on top of his other problems. He took a temporary job, he could manage, just to shut his mother up, but that still left his future as cloudy as ever, so he talked his parents into letting him escape adult reality again, by allowing him to go to school at Santa Barbara, and live there, even though there was no reason to believe he'd function any better there than at the first 2 colleges. Maybe they were hoping for a miracle, maybe they needed a break from having to deal with him all the time, but letting him go there was like throwing someone who can't swim into the deep end of a pool--and he did psychologically drown there.
At Santa Barbara his obsessions continued to spin out of control, and his paranoia led to violent revenge fantasies. He couldn't function as a student, and he wound up pretending to be a student rather than being one. Other than shopping for designer clothes, and wanting a beautiful blonde next to him, mainly to complete his "image", his thinking and emotional state was more a cesspool of self-pity and contempt for others than any true desire for a relationship with anyone.
He couldn't reconcile his fantasy of what he felt he was entitled to in life with the reality of what he was able to obtain/attain through his own abilities, which was next to nothing. And he knew he had no talent that would rescue him from a life of jobs that he considered menial or "beneath" him, particularly since he'd never earn a college degree, nor did he have whatever it took to get himself laid by a beautiful blonde, or to have one as a girlfriend, so he saw nothing but misery and suffering in his future. I think only his violent revenge fantasies kept him from committing suicide sooner.
His thinking and inner world was very twisted. Considering how long he planned his Day of Retribution, that was largely unrealistic fantasy as well--most of it could never have been carried out, and beyond the killing of his roommates and their friend, it wasn't a well thought out plan. Did he really think the women in the sorority house would just open the door for him? Considering the carnage he wanted to pile up, he was, mercifully, nowhere near as effective a mass killer as he wanted to be.
We're never going to really know why he killed the roommates, and why he did so in a particularly grisly manner with dismemberment of their bodies. I wonder if he genitally mutilated them as well, or tried to flay them? The police did find the crime scene pretty horrendous, and they didn't want to discuss it in detail. Originally he wanted to get the roommates out of the way so he could lure others to the room and torture them, not that being able to lure others would have been at all realistic either. But he abandoned that idea, so we'll never really know why he committed these particularly horrible murders against 3 people who weren't his prime targets, and toward whom he didn't express much hostility in his manifesto. He didn't want to just kill these people--he wanted to, and did, rend them limb from limb. Was it because they were Asian? The men at that party he got beaten up at were Asian too--was this his symbolic payback to them?
Anyway Foundy, I think I've gone as far as I can, and want to, in trying to figure Elliot Rodger out. I'll continue to follow your posts with interest.
