This will not happen. The author intentionally paints everyone that the MC kills as a villain in order to satisfy the power trip fantasies of readers with lower intelligence. Unfortunately this makes for one-dimensional characters, and the whole thing implausible for anyone having half a brain.Hm, I kinda want him to run into and kill someone actually not horrible for once, just for a change. Or, that at the end he realises that he has become like all the rest.
