Actually, you don't need to be a true pacifist in the neutral run to get the pacifist run unlocked later on. When I did a neutral run where I showed no mercy, but didn't look for anyone left either, I just killed anyone who stepped in my way. I killed Flowey after that aswell. Then I replayed it again, went through in a pacifist way, but didn't have Floweys guidance to visit Alphys, I just went back to the area myself, before hearing the monsters talking about Asriel, and before the judgement. I just went straight for the date and the lab, and then I seemed to have skipped the story of Asriel and the judgement in that run.
