Warning: spoilers ahead for Choujin X chapter 13!
Mangaka Sui Ishida always portrayed Ken Kaneki as the only hero who could bridge the series' titular monsters and humans together in Tokyo Ghoul, but the hybrid's efforts culminated in numerous deaths on both sides, while Ishida's newest hero Tokio Kurohara in Choujin X is taking active steps to prevent as many senseless deaths as possible.
Like Kaneki, Tokio would have gotten terribly lost after transforming into one of his world's titular superpowered beings, but he luckily stumbles upon his world's version of Anteiku, known as Yamato Mori, which is an organization that nurtures good Choujin. Yamato Mori holds certain ideals to maintain peace, and helps Tokio understand his new place in the world, but whenever Choujin go on a rampage, the organization strives to annihilate them. Tokio later finds himself caught in a battle between Yamato Mori and the rogue Sinker Choujin (aka Tezuya Shiozaki) in chapter 13. But Tokio can't accept this after learning that Tezuya has been struggling to take care of his younger siblings because of his powers. He decides to confront the powerful Choujin in an attempt to save him instead of letting Yamato Mori kill him.
Although Tokyo Ghoul's Ken Kaneki strives to create a world where both ghouls and humans can live in harmony, he adopts a ruthless persona early on and slaughters anyone who threatens his friends or the way of life espoused by Anteiku, which shelters and helps other ghouls in need. This mentality leads to the deaths of numerous ghouls and humans. Before this violent shift, Ken Kaneki was much more focused on suppressing his ghoulish urges than anything else. Even when his friends were in danger, he tried stopping himself from embracing his newly gained powers, but Ken Kaneki eventually gave in, lashing out with terrifying aggression that left his enemies severely maimed.
In Choujin X, upon learning how to appear normal in public as a Choujin, Tokio hasn't focused so much on suppressing his powers like Kaneki did, as he still hasn't unlocked his true potential. This allows Tokio to spend more time worrying about what he should do with his new identity as a Choujin. As a result, he's now actively going against the very organization that brought him in to save the rogue Sinker Choujin that is threatening to destroy the one place that is keeping him stable. Kaneki would have undoubtedly succumbed to the ghoul side of him if he were ever in the same predicament and eliminated the threat. But Tokio is more worried about saving this other Choujin than protecting what's important to him.
This isn't to say that Kaneki never cared about enemies, especially during the early stages of his life as a ghoul. He's had to show great restraint in dealing with human officers of the Commission of Counter Ghoul (CCG) that investigates ghoul crimes. Luckily, Tokio has yet to deal with such a dynamic as the relationship between humans and Choujins isn't as tenuous. There also isn't a CCG-type organization.
Tokyo Ghoul's Ken Kaneki faced an additional obstacle that Tokio has yet to deal with. There isn't an inherent urge in him to kill enemies or devour humans. When Kaneki first became a ghoul, he dedicated most of his energy to suppress these sinister feelings instead of help rogue ghouls. And when he embraced his ghoul side, he straight-up murdered them, a failing he was later forced to contend with near the end of the series. Tokio Kurohara's only struggle in Choujin X is learning how to actually unlock his true abilities, which he has no reason to fear. This allows him to help those in need even if they are currently a threat. In other words, Tokyo Ghoul and Choujin X mangaka Sui Ishida is essentially giving Tokio Kurohara more tools to be a better hero than Ken Kaneki ever could.
