The story isnt bad but the mc is the kind of guy you hope to see killed he has no trouble watching women and children get torn apart by zombies he rapes and does other things there is NO way to like this guy
As much as you say there is no way to like this type of protagonist, (based on the points you mentioned) I hate to inform you that you’re just wrong.
There are a lot of people who like cold, emotionless protagonists. On the other hand.. HE IS SO GOD DAMN STUPID!
