I've yet to play Yume Nikki, but is the yandere tag applicable here? At least if you think of it with the rule of thumb, 'tag what you can see', it doesn't fit.
Though yandere, tsundere, moe, etc tend to be overused in tagging and discussion anyway...

Debatable. There's zero dialogue - or even monologue - in the game, so all characterization is by inference. There are, however, several parts that necessitate stabbing the shit out of a lot of dream creatures in order to get all the accessories, which you must do in order to complete the game.
Also, stabbing Poniko is one of the essential parts needed to meet UBOA, so you could say the game encourages you to play it as a yandere kind of thing.

Cute girl, bloody knife, psycho look on her face... Yandere seems obvious enough.
My point was more that yandere is a very specific condition that considers the motivation of a character's violence to be of great importance. A yandere character acts due to feelings of love or romantic jealousy. Of course a yandere character is a sociopath, but the normal motivations of anger, fear, greed, etc don't apply. Simply being homicidal is not sufficient, though that seems to qualify it for tagging on danbooru.
Naturally, motivation is difficult to tag, and a purist definition of yandere would tag much fewer images than there are currently. Instead, some would suggest the yangire tag to be more appropriate when the motivation is ambiguous.
