Common theme of distrust in Ryukishi07's works

[onorub]

Having played Higurashi, Umineko and Rose Guns Days, i felt like a big similarity between them was the theme of distrust. I'll try to explain while giving as less spoilers as i can, but be careful just to be safe.

For Higurashi:

Spoiler

Rika would keep dying because her friends would keep distrusting each other and it would distract them from what is actually going on, and once the friends erased that distrust, they were able to find out who the mastermind is and go against him.

For Umineko:

Spoiler

The main issue of the series is the distrust that Ange has towards her family by believing that one of them is a cold-hearted killer, and episode 8 is all about her letting go of that distrust to move on with her life.

For Rose Guns Days:

Spoiler

The biggest thing that kept the japanese from standing up to the chinese and the american was the distrust that the japanese had for each other, which ended up causing the collapse of the tradicional japanese society in the story. That is seen with the biggest hurdles for Rose being the distrust that not only the city merchants, but her own right-hand man had towards her.

So, can you identify this theme in Higanbana and Iwaihime as well? Or do you feel i'm mistaken?

Edit (jan 4th) - Having played Higanbana:

Spoiler

A fair amount of students have some sort of distrust towards society that lessens their will to live, making them suitable prey for the youkai of the story.
