Here's all his unarchived Reddit coomposts. It's important to archive this because we cannot understate the role pornography played in this young man's psyche:
Also, here he states his age was 14 as of 2021, making him 16/17 as of this shooting. This is really telling, not just because of the extent of his depravity at such a young age, but also because the Plebbit admins are negligent in restricting underage users from seeing porn. His account should have been banned, either for being underage or LARPing as underage, as soon as he went onto a porn sub after this comment.
I didn't recognize the character by name at first, but a quick google search, yeah....honestly its weird and creepy how so many trans / gender people love that kinda shit (evil charecters). Reminds me of that short fat otaku video "identification with evil", almost like a subconscious admittance that despite them trying to brand themselves as good, decent, not evil, ect, that they are still in fact evil, but just dont want to be persecuted for being evil.
It's typical incel behaviour, really. Look at the types of guys who idolize the Joker (always the dark edgy versions, never the fun versions), Patrick Bateman, Tyler Durden, and so forth. They're all sociopathic, porn-addicted incels who believe, while in mommy's basement, that they're victims of societal oppression. They want that narrative to be reinforced, even though what's holding them back from their goals -- whether it be academic goals, career goals, or romantic goals -- is their own entitlement, bad attitudes, and unrealistic standards. They want quick, easy money (which is why so many fall for crypto and dropshipping scams) and cry when they have to work for a steady living like everyone else. They get mad when they can't find a woman who has no mature interests and is also willing to bring home a salary, cook, clean, look good, and have porny sex at the drop of a hat. Of course, these types of males tend not to do well in academic settings because having to put in lots of hard, slow, and unglorious work runs counterintuitive to their worldview. They turn to these characters because they wish they could take their toddler rage at not being special out on society and have this rage be justified and glamourized. This guy probably felt that way because the porn was teaching him unhealthy messages about sex and women and frying his dopamine receptors.
That said, is this guy even trans? He seemed to have been some sort of repressed non-binary person at best. The friend quoted earlier who received a goodbye text from him referred to him as "he"; you'd think a close friend who was deemed worthy of such a text would use their preferred pronouns. He seemed to have been obsessed with femboys and likely gravitated towards gender non-conformity due to that. I assume it was just limited to his online activity. Too many young people are buying into the idea that any sort of non-conformity with gender norms means you're trans or non-binary, especially if you're terminally online and easily influenced like this dude likely was.
He was a GAMP, so he likely would have trooned out because it would allow him to live out his coom fantasy. GAMPs tend to be very low-effort troons since they fetishize being feminized males, so just growing out their hair and crossdressing satisfies the fetish. If he was naturally gender non-conforming, he wouldn't have had the femboy fetish because a feminine male wouldn't be exotic and new to him. The tranny crap was limited to his online activity because, again, GAMPs are low-effort (he said he wouldn't transition if he didn't end up pretty, and you can bet he wouldn't put in the effort to pass) and he probably wanted to hide his desire to transition from his parents. If he came out as a tranny to his parents, they probably would have been surprised and maybe questioned/gatekept him because (from what we can see) he was a stereotypical teenage boy who was proud of being a masculine cowboy and had no typical signs of gender dysphoria. GAMPs HATE being gatekept and told they're just cis males because it's a narcissistic injury.
