Its just his opinion, why you comparing him with a CHARACTER? And yes for now i hate this mc because he just know how to yelling and blaming others even his mom too. Regret? Why i/him must regret? Even mc become badass or beast he is just lucky because he had a system from nowhere, it's just a comic (manhua/manhwa/manga/whatever) why are you use this to judge someone, the reader can have their opinion
