I absolutely agree.
And I actually think this is a really important aspect of their relationship and any interactions they’ll have in the future.
sans-san said it really well in our conversation about Eto and Kaneki parallels and their goals the other day: “he did the same as her: he became cruel in order to defeat the wrong in this world.”
I think that’s ultimately their biggest parallel, and it’s why Eto is so interested in him after the Aogiri arc. She sees him going through the same stages she did: realizing the cruelty of the world, the necessity of becoming strong, consuming others to gain that strength, and then ultimately enjoying the power over others.
But, the difference is, whereas Eto was alone, Kaneki had friends who supported him. He had Anteiku (and Yoshimura telling him not to throw away his human side), and he had a lifeline that tied him to the human world, even after everything he went through: Hide. (When he thinks about losing his place in the human world, he literally just thinks about not being able to be with Hide anymore.)
And then when he starts the serial cannibalism, the revenge, the cruelty after the Aogiri arc, he abandons Hide, and he abandons Anteiku: the place that allowed him to be a ghoul and also be with Hide.
So I don’t think it’s an accident that Hide, Kaneki’s tie to the human world, shows up in V14 when Kaneki hits a low, and that when Kaneki starts to lose his grip on himself, Hide’s voice is the one that talks him through V14. And then ultimately Kaneki’s descent into the ghoul world is halted.
So basically V14 ends up being a good thing for Kaneki, if the alternative is losing his humanity like Eto. Or, like the half-ghoul Eto made specifically to replicate Kaneki, Seidou.
I also think Seidou is proof that this was the path Kaneki was on, and the path Eto already walked. And that Eto probably wanted Kaneki to end up the same way.
Woops this got a little longer than I intended.
