I like that view on Yandere. Most people like them just because they seem different/new or psycho, and not what goes on beyond the disturbed exterior.

Yandere (almost) always have a reason for their behavior, unlike the tsundere that are sometimes just bitches. I can't really blame such tsunderes though, because they are characters written for a shallow and generic story that simply required a character slot fulfillment of this archetype.
