Review Detail of UrizenVergil in Re-Born in Demon Slayer

How is that in any way related to how bad or good the fan fic is?, that's only what the mc did

it is realted as you are trying to show that mc goes towards the path of revenge by shouting that he will kill the person who did this to his family and trying to gain sympathy from readers but he himself let them die without a second thought just because he wanted the plot to be the same It is very poor characters development and start of a disaster
