Amadeo was born in Lastwall, and all his youth he was educated with stories of good deeds and duty.
His mother was a paladin and his father a cleric of Iomedae. Both his parents loved him dearly, though they hadn't much time for family life.
His older brother, Stavro, was a skilled fighter, which he greatly admired.
One day, his mother disappeared while on an expedition beyond the Wardstones which guard the ruined realm of Sarkoris, now subsumed into the abyssal pit of the Worlwound.
His father wanted to go in search of her spouse, but Lastwall's military command forbade it, because they feared a major assault was coming from the demonic forces and they needed all the able-bodied men they could get to defend the city walls.
So his father stayed in the city and prepared for battle.
But Amadeo's older brother couldn't resolve himself to abandon all hope, so he set off alone in a desperate expedition to rescue their mother.
Amadeo wanted to come with him, but Stavro sneaked alone under the cover of the night to prevent it.
Then the demonic assault came, and Amadeo did his part. The demons were repelled, but many were killed, and his own father was grievously wounded.
His father summoned his son to his deathbed to bid him goodbye.
"I wish you wouldn't die" said Amadeo.
"I give my life to the greater good" answered his father. And then he died.
That night, while Amadeo was awake mourning the remains of his father, an eldritch vortex opened and he saw coming out from it an evil apparition in the likeness of his mother.
She taunted him, saying she had flayed Stavro out of his skin when he came to rescue her, before eating him alive, and that she was now a good whore servicing the mighty demon lords.
"Iomedae, save her !" pleaded Amadeo.
The goddess didn't respond to his pleas, but Lastwall's soldiers, summoned by his cries, ran to the scene and were able to destroy his mother.
Amadeo didn't sleep for a full week after all that horror.
Finally, he was able to fall asleep only after a singular train of thought had bore itself into his foggy mind.
There's no greater good.
Only the good you do to yourself.
And the good you do to those loyal to you - if you're loyal to them (and you should be).
From this moment of realization on to the present day, these have been the core tenets of Amadeo's personal philosophy of life.
Personality hints:
Amadeo likes to live the good life, and is a little bit obsessed with amassing wealth. Besides that, he appears as a charming and pretty tolerant criminal.
Unless you betray him, in which case he becomes a murderous fiend.
Owing to his education, Amadeo is a very religious man and a worshiper of Callistria.
He has a strange sacred/casual relationship to his goddess, which could be summarized as: "I scratch your back and you scratch mine."
He has set his mind to becoming a criminal lord and he is working hard to fulfill that goal.
