Isn't Elliot Roger the 'classic' profile of the explosively murderous/superegoic sociopath, here a juvenile manifestation of a cross between Travis Bickle in Scorsese's Taxi Driver and the killer in Michael Mann's Manhunter, while further actively 'nurtured' on a myopically cyberspacial diet of manically misogynistic and racist ravings from assorted unhinged "man" forums and websites. His ravings are much like those of numerous of these infantilist internet posters with a pathologized paranoiac-persecutory fantasy formation.
The kid who was never properly socialized into young female company, but who instead spend his time daydreaming about the 'perfect' relationship with a (white) girl, the kid who was always told by idiot adult others how "special" he was, how 'superior' he was to everyone else (especially those of other minority groups), the kid whose whole self-image (Ideal Ego), of how he demands others to see him - his infantile narcissism, his little lost boy self-pity and sulking - depends on the fantasy of the female other as redeemer who will make him feel 'whole' again. But when this doesn't happen, as it never can, being impossible, being a daydream, being his fundamental fantasy, he explodes in aggressive-violent rage. Attempting to push women off dangerous ledges at a party (as though such sociopathic violence is normal, he thinks), and, when restrained from doing so by others, retreating into the corner to sulk, to cry, such sentimentalism addressed precisely at the imagined Other who will 'make him feel whole again', so that he can resume his violence again, is the means by which it is enabled.
It was the grotesque disparity between his daydreaming about his ideal relationship (just as with Travis Bickle and the killer in Manhunter and countless other examples) and the actual reality, his chronic resulting inability to socialize (the daydreaming - the fantasmatic-real - was what prevented this, setting up a permanent resistance to doing it, fearing it), to form relationships, that provokes the raging psychopathic response; it was his attempt to actualize in social-symbolic reality itself his pathetic, Mills and Boon, wishy washy fundamental narcissistic fantasy of the perfect relation with some image - a desire directly manufactured by the culture itself, by the dominant ideology - of the passified, mortified, subservient Barbie Doll other (see below at 1.), the obscene, nightmarish disparity between the two, that then found expression by displacing his paranoia onto the demonization of imagined evil others who are plotting against him and stealing all his posited enjoyment (Chinese, blacks, women, the very people he targeted).

1. Killer Elliot Roger wrote in his demented 'manifesto' of when, as an awkward 14-year-old school-kid, he was obsessively fantasizing about a 13-year-old blonde girl, but who he later compulsively and pathologically demonized : “The funny part of this is that I had a secret crush on her. She was the first girl I ever had a crush on. To be teased by the girl I had a crush on wounded me deeply.” But later: “I hated her so much, and I will never forget her. I started to hate all girls because of this. I saw them as mean, cruel, and heartless creatures ... The way I was treated by girls at this time, especially by that evil bítch, sparked an intense fear of girls.” Until finally his sclerotic resolve: “Women’s rejection of me is a declaration of war. If it is war they want, then war they shall have. It will result in their annihilation.”
