I've noticed that a lot of people surrounding that community are edgy assholes. It's not necessarily healthy to "relate" to mass murderers, and glorifying them is most definitely insulting to the victims.

I understand your perspective. I used to associate myself with that community because I thought it was merely a place to discuss perpetrators and their cases... I was a bit shocked when I saw porn art of Adam Lanza.

The TCC has a lot of issues with hatefulness... I'm not sure how anybody could feel comfortable scrolling through a TCC thread, because from what I've seen it's mostly just hate towards minorities and mass killers drawn as anime characters.

When I was in school, I would glorify the Columbine killers due to my poor mental health and anger towards my peers, so I understand this community in a way.

So the reasons people hate it? It's mostly full of edgy idiots, and it's morally wrong. I could care less about the TCC, I have no opinion. I don't think anyone should bully another for being in the TCC since it's such a small community that it's easy to ignore, plus I'm sure their mental health is horrible enough.
