People are collapsing, only love Valkyrie

What should I do if I travel to the collapsed world and become a Catholic bishop?
In this broken world where a bunch of people want their own lives, Otto can do nothing but hug the thigh of the system wife.
But... there seems to be something wrong with your own system?
"Ding! Boom!"
"Congratulations on getting Judas' oath!"
Well, the once glorious God's Key, a good thing, it is my duty to recast the glory of Judah.
But why did the courier Teresa kick open the office door, hit Judas on my face, and shouted, "There is no prince in his 40s in the world!"
"Congratulations on getting the Heavenly Fire Sacred Judgment!"
Well, the God's Key with the strongest firepower is a good thing.
But why the way to receive it is to beat Siegfried violently, and then take away his sky fire?
How can such a kind person like me steal other people's things?
"Congratulations on drawing Cecilia Shaniat!"
?
Siegfried over there don't leave yet, you still haven't given me something.
