She had seen too much
Fabian was a normal young peasant, barely surviving at a young age. When his mother passed and their abomination of a father, who only thought of himself, all Fabian has was his older brother, Rufus. His older brother stood like his parents, working manual labor at a young age to raise his little brother.
But life wasn't fair.
For these boys, no matter how they tried to live morally, it was never enough. Thus, Rufus, who thought working hard was the way in life, had to resort to stealing to feed two mouths, risking his young life day by day just so the two of them survived.
Things weren't particularly good, but they were surviving. Until years passed and Fabian became the target of bullying. When life was hard, people tend to unload their anger on those weaker than them. Sadly, Fabian wasn't as strong, brave, and capable as Rufus, and was a victim of constant beating for no reason.
