For a calculative murderer, mc sure complains at every little thing.
Your main character surely is developing the other way around.
Mc is becoming more annoying every chapter and there are so many contradictions and nonsensical attitude 'development'.
Also the mc doesnt have a clear goal except for survive. This equals to a disaster of a novel.
For someone who were able to get revenge to every little bad thing (except his company) to him his attitude doesnt make sense yoy should have said that he has a mental disorder from the beginning.
Im dropping this. But good luck to you author and i sincerely wish that you could improve more in writing.
