Well, the story is about an encounter with a serial killer, so of course there is too much of the killer in it. The comment you responded to is just trolling around, and getting downvoted for it. I still don't see what you mean, sorry.
The story is written as if it were fan fiction of the fan of the killer. Then there is a comment on it saying how "perfectly wonderful" and "absolutely magnificent" the story is. And then there's this guy, who isn't trolling(from a deleted comment I found out he didn't read the entire story), and inquires about the writer's same-sex relations after the encounter. As a bonus, there's also an article elsewhere "Why hasn't California executed Randy Kraft?", in which there's a comment which describes what the killer is doing, and urges people to write and send books to him. This all turns my stomach. It's morbid.
I know he didn't read the article. I guess technically what cam4er is doing would be called shitposting, but I tend to consolidate these related behaviors under the trolling category. Fact of the matter is, and I think we agree on that, his posts are low enough quality to get him banned.
I found the article itself very interesting, actually. Morbid of course, it's a serial killer story. I didn't get the impression that the killer was idolized though, it was more a description of how far almost-superhuman charisma can go and what it must feel like to be on the receiving end of it.
I read the "perfectly wonderful" comment and took it as a compliment on the author's writing ability. IMO he did a great job conveying an unusual social and emotional situation.
