Achievements not achieved yet

I am looking at Steam achievements for first time and it is almost 10 days since release and there are 4 achievements nobody got yet, though there are reviews claiming to finish the game, but probably rushed just through main quests, as they seem to take around 25-50 hours to complete.
Here are achievements mentioned.
Judas. Betray your friends in a certain quest.
Pilgrim. Find all shrines and crosses.
Merciful. Don’t kill anyone except one person.
Completionist. Complete all quests.

The achievement I wanted most was Merciful.
What is even more weird is people did not discover all places when Pilgrim is not claimed yet.
Judas is probably one of those when you are trying to intentionally fail quest.
Moreover, it’s obvious nobody played game enough to just do everything he can, probably due to bugs.
All reviews should be updated after people finally get those 4 achievements and will see the whole picture and not just a little bit. It seems to me people just rushed reviews, I am waiting for patches and it only seems right to do so for people who are misguided and down by reviews that are so shallow and incomplete.

Judas is based of the fritz and Mathew questline.

Thanks for info. So everyone seemed to enjoy throwing poop and thought it was right.

What? You can’t throw poop at your friends geez…

I think not. Nobody did it so far.

I think it could actually be the throwing poop at the persons house quest and you betray them.
