This was on the Genocide page. Have not seen a video of what Flowey says in this instance anywhere, and there does not seem to be any distinction between this condition and aborting the Route "midway through" in the bullet below this one. 
 * If the Genocide Route is aborted before going to New Home and Flowey is spared, Flowey chastises the player for killing other monsters, and requests them to reset the game and replay the entire Netural route without killing monsters.
