Entertainment: I Know a Little Bit of Everything

Someone comes with a system to seize the body, so it makes sense for me to beat him to death. People were beaten to death, so it makes sense that the system would be crippled. The system has been crippled, so it makes sense for me to take advantage of it. I have a system and I know a little bit about everything, so it makes sense. Therefore, I am the protagonist. Quite reasonable, right?
