Honestly, we do not know enough about Chara to say why they killed monsters as well as humans in the soulless pacifist run. Perhaps they never had sympathy for monsters and instead just wanted to destroy all of humanity and would do anything to reach that end. With this assumption, we can see that the Chara/Player complex is just power hungry and always wants more STATS.

Or, Chara could just be messing with the Player and reminding us that we already killed all of our monster - friends once. It depends how you interpret Chara.
