That only supports the theory that Chara might be the narrator, which is basically proved since flowey talks to "you" at the end of the pacifist route. But now follow me on this. In the Genocide route, they actively.

-Send commentaries about getting other monsters out of your way, don't hesitate and how useless monsters are once they served their purpouse (the player gaining LOVE from their deaths).

-Mortally hounds Sans (It was them evidently.)

-Kills Asgore.

-Dismember Flowey after he implores to you.

You have 0% of control over these actions, so it's pointless trying to discuss if Chara did or did not do these things. Only three beings have control over the game: Frisk, Chara and Flowey. and since Frisk is unable to chose the last three kills, it WAS Chara, and maybe yes, they are not completely evil, but in the Genocide route, although they are influenced by Frisk, they still become a hearthless person with hungry for power.
