Imagine your favorite character buying merchandise of themself, like figurines or posters, from their show/book/etc because they’re “just a bit curious" (but you suspect that they’re being narcissistic)
An incomplete list of Tokyo Ghoul characters who have murdered a person for some reason other than strictly survival (where mental illness and skewed perceptions of the world are not considered) so you can add them to the list of people you will never forgive or allow redemption for along with Tooru -
Kaneki, Touka, Ayato, Yomo, Yoshimura, Koma, Irimi, Tsukiyama Shuu, the entire Tsukiyama household, Eto, Nishiki, Takizawa, Shikorae, Naki, Miza, the White Suits, almost certainly Hinami though it isn’t shown on screen - though certainly as an accessory, Chie Hori as an accessory, obviously Furuta and Kanou, obviously Yamori and Torso, not even gonna go into the obvious ones. Like the Clowns.
If you include CCG officers who were “doing their job” but went above and beyond what was strictly necessary:
Urie, Shirazu, Suzuya, Mado Kureo, Mado Akira, Kijima and Tokage and pals, Matsuri and Tsuneyoshi Washuu for sure,
If you don’t consider “I was just obeying orders” or “it was just my job” as defenses then:
Every CCG agent
Please enjoy your cast of possibly Banjou, maybe but not likely Hide, and Momochi Ikuma from the novels.
Seriously if you are all “That’s it Tooru is beyond redemption” but you consider Shuu or Nishiki okay people please reexamine why this is.
