Can you tell me what you don’t like about the mc? Because if you’re afraid that the mc gets bullied because of his ‘pacifism’ or gets in trouble because of that, then you can rest assured. This is not that kind of novel. I suggest reading more.

First off a pacifist in a post apocalypse is not possible. Especially the type you have portrayed him as. He would have been dead before he reached his teenage years just from infighting or nefarious people. Either that or starved to death. No vegetation in your outerlands. Also just the concept of the grim reaper would mean that the power he took would have rejected and killed him because he is the complete antithesis of the grim reaper. it would be like matter and antimatter colliding. The rejection would be violent. The other things driving me nuts about him is the constant rhetoric from him about not liking blood, suffering and so on. Pretty much all that he says in most cases. Also something that the grim reaper is a big deal about. The grim reaper was the reaper of souls on the battle field, sowing death, blood and suffering before he took the souls with him to suffer more in hell. Your story does have great promise, and it is your story and not mine so my opinion doesn't really matter. But since you asked I figured I would state my feelings about it for you. Keep up the good work because this is only my personal opinion.

Pacifist: a person who believes that war and violence are unjustifiable. This does not mean that they cannot kill, not even in the slightest. You have conflated both the meaning of pacifism and the concept of grim reaper heavily with other iterations of them. The grim reaper, at least in any of the depictions I’ve ever read or seen, is not a being that goes out of its way to torture people. In fact I don’t even think “hell” as a belief system has a grim reaper involved in it, they take souls elsewhere wherever that may be… I don’t really know if the novel is good, but a pacifist with the power of a grim reaper makes sense. You don’t do anything until you’re justified to do so and that fits the definition of both pacifism and the grim reaper
