I think she was made to actually appear and talk to players. The child appearance is probably to make it easier for people to trust and connect with her. People like lolis cute things, after all.

Just make it equally sadistic for that end. You know, like Left4Dead's Director.
The game was supposed to be a proper MMORPG so Yui was there by design. Kayaba just turned it off. Cardinal should still be under Kayaba's control anyway. It was probably easier than modifying it.

I think "normal" in the AI's perspective is how people should have been in the game without the death game modifications. People should be enjoying SAO after all. I agree that Kirito and Asuna are not normal considering the situation.

To the program she became a mother figure to literally 24 hours ago. What a lame-ass attempt at an emotional pull. It is utterly impossible to believe that she could have gotten that attached to Yui in less than a day, particularly if she is as "sane" as Yui claims the two of them are.
I absolutely agree with you. Forced drama sucks.

This is probably one of the worst things in the story. It is utterly stupid and could have been done in a more believable way, like Yui managing to save herself after being convinced by the couple to stay with them or something. An AI doing it is more believable than Kirito who was never shown to have programming capability. Why the hell would the admin access still be there anyway if the AI itself visually disappeared?

This has always been my most hated side story retcon in the novels. The entire Yui thing should have been scrapped.
