@sylvacoer I agree with what Lucrecia and Nikoko said. Also want to add a few points.
Every time something goes
stupidly wrong, its usually because of power and/or religion. (it has to be
stupid.) This is because of how our minds work. We are shackled by desires.
Example. A poor person tend to think more about how they spend their money compared to rich person's impulsive spending because a poor person can't get everything.
Similarly, a powerful person would have less issues screwing people over to get what they want because "I am powerful, nothing can touch me! Muahahaha". While the "very religious and faithful people" (take this with a grain of salt) would think "God is almighty and
everything goes according to his will". By which i mean, they stop using their braincells and praise/blame God for everything. ( I can give real life examples if necessary)
So if something goes stupidly wrong, its usually because of these people not having sufficient empathy/risk management or ungodly amounts of overconfidence (Read isekai stories where Kings purposefully offend certified strongest existence in the world).
Now, one of the most popular fictional settings in Medieval Europe. So religious institutions (which usually is the faux Christianity because of settings) are usually BOTH powerful and well... religious.
In other words, they become cannon fodder.
