Little spoilers
To be honest, I don't think Sam's religious views make any sense. If Sam believes that God is cruel and is constantly afraid of punishment because of what he has done, then he should be afraid of committing other sins just as much because God will punish him because he is cruel. At the same time, he criticizes Saint Paul saying that one must radically cut oneself off from sin and the submission of the flesh, saying that the teaching of Jesus said something different. Suggesting here that someone can sin from time to time and that's okay. But this has nothing to do with the cruelty of God. If God allows sin, and Jesus somehow implied it, then that is against harsh judgment and cruelty.
The whole shed scene in the latest update is also weird to me. Sam's views make sense for this scene, but they seem detached from other moments where Sam is terrified of God's judgment. I think the whole polemic with Saint Paul was written for this one thread, but in isolation from the whole story.
Of course, I know it's still just furry visual novel, but I like being consistent in how the characters are written. This is important, especially in a thread that is likely to be relevant in Will's route (I think). I'm still enjoying the game, but I'm starting to notice some turns that I don't like.
It is possible that I misunderstood Sam's message due to the difficult words and my language barrier, but I tried to understand this passage correctly.
