Review Detail of Silakai in Void Evolution System

Pretty good up until chapter ~128 or so. He decides he's going to use a sword art that turns him into a sociopath who can kill anyone with no hesitation or remorse. He says that emotions hold him back and he wants to be an emotionless monster with everyone except the few people he's close to. Not a healthy mentality at all. Everything else was great. I just can't get into a story with an immature MC wanting to be a sociopath
