Mini analysis of Hanekawa from what I got (Monogatari spoilers until Nekomonogatari): So basicaly Hanekawa is kind of a sociopath, in the sense that she really doesnt feel pity or guilt from the actions she did, like she didnt feel bad for the dead cat or Araragi becoming a vampire, she always wanted to be and because of that acts like a normal girl, thats why she buried the cat even though she didnt care for it, the reason why she adopted the cat was because she felt stressed for the fake mask that she always has on, her cat version is her real self so basically shes a crazy person, kinda dissapointed because I loved how kind she always was.
