I feel like that wasn't the best choice... it's best to have a mc who develops his mentality through battles as well... now, his emotions will be stuck without any growth. And you also cut a lot of juicy content with this skill... readers need to feel the emotion when the mc is fighting but now, you can't use words like panic, terror, or reluctant in battles because he is supposed to feel nothing. Unless you put some restrictions on that skill, then I can determine that this novel got 20 percent less interesting... we'll see how it goes.
This feels like a huge mistake in writing, even having the choice of that skill is a mistake from a narrator standpoint. You just cut out any emotional development and training from the MC, there is never going to be any emotions connected to fights. The MC is essentially stuck and there is nothing as an author you can do now to take that back. The only thing this does for the story is playing into readers pathetic power fantasies of humiliating others, never caring about the world around them, being brutal against people etc. These people this skill cater to don't read for a good story, they read to live out stuff they can't do irl.
Okay first of all when the author adds more emotion and mental struggles you guys call the mc brain dead or a cry baby. When he makes mistakes and doesn't think you criticized him but now when he's doing something to fix it you now start switching up? You want the emotion and rash actions now? Make up your minds or just enjoy the story.
