As far as I know, no. Considering one FLEEs from every battle that they can (minus boss battles and Toriel's battle), however spares all monsters when they can't flee, it will ultimately turn out to be a "Pacifist Neutral" run (Which is basically sparing everyone, but not completing a True Pacifist Route). If one follows a True Pacifist Route, chances are everything will be normal, except most if not all monsters have white names as opposed to yellow names.
