What's the meaning behind Yuzuru's photographs?


A few scenes after the failed suicide attempt of Shouko, we see Yuzuru telling
her mother something about the pictures she was taking and how she was trying
to prevent Shouko from killing herself. Can someone explain that to me?




From to the [wiki](http://koenokatachi.wikia.com/wiki/Nishimiya_Yuzuru),

> Her hobby is taking pictures of dead animals, with **the intent of showing
> her sister how horrible death is**. The purpose is to **discourage her
> sister from killing herself**.
