Note that doing a normal Reset is not a requirement for completing anything, except in the instance where you've completed a Neutral route and have killed at least one monster. So you could do a normal Reset and start a Genocide playthrough. Likewise, you can do a normal Reset and get the True Pacifist ending (assuming you've messed up what is usually referred to as the "Neutral Pacifist" run).
