Is A Useless Villain Worth Reading?

Overview

Dong-Jin Kim reads as a typical moody high schooler on the surface. Underneath, he's a powerful psychic who considers himself a villain -- someone actively working toward humanity's destruction. There's a catch built into his power, though: every time he kills with it, time resets. Trapped in that loop, his method for finding out who's actually responsible for his situation is the only tool he has: killing the people around him, over and over, narrowing the possibilities one reset at a time.

It's a time-loop premise that refuses the genre's usual comfort. Most loop stories eventually let their protagonist become more heroic as they learn the rules of their reset; this one keeps Dong-Jin's chosen method genuinely disturbing throughout, because the tool he's using to investigate is also the thing that makes him a villain in the first place.

What it does well

The story's biggest strength is its refusal to soften Dong-Jin into a more palatable anti-hero. He kills to gather information, the story doesn't pretend that's a morally neutral action just because the reset button exists, and the tension of the series comes directly from watching a self-declared villain try to solve a mystery using the one method he has, even as it keeps implicating him further.

Tying the reset mechanic to his specific power also keeps the loop structure from feeling like a consequence-free sandbox. Each kill costs something -- it's the trigger for the reset itself -- so the story has to keep justifying why he's willing to pay that price again and again, which gives the repeated structure real weight instead of treating it as a video-game retry.

Because the series is complete, the central mystery of who's actually behind Dong-Jin's situation gets an actual resolution. Loop stories live or die on their endings, and having the full arc available means the payoff can be judged on its own terms rather than left as a cliffhanger.

Where it falls short

Dong-Jin is built to be alienating, and that's a deliberate choice the story commits to, but it does mean readers who need some emotional foothold with a protagonist may struggle to stay invested through the earliest chapters, before the full shape of his situation becomes clear.

The loop structure also means some scenarios recur with variations as Dong-Jin tests different approaches, and that procedural quality can feel repetitive in the middle stretch before the mystery's resolution starts to come into focus.

Verdict

A Useless Villain earns its discomfort honestly, giving its self-declared villain a genuinely unpleasant method and refusing to launder it into easy heroism. It's a strong, complete time-loop thriller for readers willing to sit with an unlikable protagonist in exchange for a mystery that actually pays off by the end.
