Fending for myself

My book is about Jake (main character) who did save the world as a general of the army, not giving a fuck and doing everything on his own. He regrets saving the world afterwards, because he thinks only bad people live there, and so he starts too lose his feelings towards everything, which he tries to avoid. And there will be an antivillain who tries to get justice by killing people who kill people.

And it includes my psychological principle of A-siders and B-siders. Two types of people. Will be explained there. It is pretty negative, though.
