He expressed to others that he wanted to be famous. The lyrics of that song deal with loneliness. My first instinct is that he's one of the infamous incels, since these are common themes that come up when one of them goes on a destructive and/or murderous rampage. The difference is that he didn't target women in his rampage, and at least a year ago he did have a girlfriend. The next question that comes up is, was that site one of his past customers or a competitor that maybe got one of the gigs he hoped to get?
