Well, the apathetic, ruthless and evil protagonists are very charismatic, so I will make a list with protagonists that will give you a different flavor !!

Also the list is not made up of any novel with those labels, obviously they have to be the most outstanding !!

Some may not seem at first like this, but thanks to an excellent character development we can enjoy these protagonists.

I will put novels of more than 1000 chapters or that are complete.
This list has neither better nor worse, judge according to your criteria.
