I disagree. IMHO, it’s about the killer having a personality disorder full of rage and anger with truly nothing but their own lack of skill sets & the inability to assimilate into society fueling them on. Like the world owes them something. In reality, they have a superiority complex & all the while barely challenging themselves to the real issues we all face that cause the most angst.
In my opinion, this killer spends a lot of time in his room playing violent video games, smoking a lot of weed, and wishing he was a somebody without investing in the character-building actions and skill sets needed to really be a contributing member to society. So he lashes out because he thinks he’s so special. It’s really sickening to those who struggle and do the right thing every day while still remaining kind, charitable, productive. Ugh!
Yeah, we should feel sorry for the ASPD spoiled, self-centered brat whose only power comes from taking the lives of the innocents. Not.
Okay, ATOH, I'll agree to disagree. I don't think he has a "room" or smokes pot. Looking at him on that first video, he's on a mission, but jmo.
