The Karma system(Don't read this

Let's just say this is a rough draft, MY FIRST NOVEL This is my first novel so bear with me, also I'm making this mc EVIL like Evil Evil so if you don't like evil protagonist don't read this, and you grammar Nazis give me all your criticism it helps a lot, another thing is I'm doing this for fun so if you don't like it too bad. One more thing can you people (who do read this) explain commas to me, I find them difficult? I'll start writing the novel on a later date if I feel like it.
