Nothing too new, this is a very common fan-fic in my opinion. The MC is born as a gentle god (usually in fanfics he would be a demigod) he befriends the gods, he does something "wrong", he receives a greater punishment than he should, he becomes a brutal / cruel person and dominates the Olympus. THE END [google translator] Of course, the story is much more developed, but I want to summarize.
Liked it!
LIKETheGodSage:sorry if this sounded Aggressive but like.. what you said isn't the plan and will never be the plan... otherwise i'd out Brutal mc as a tag... he's just... a god?
