I'll throw my hat in for a cleric of Asmodeaus that I submitted for another campaign. I can link the die rolls if you wish.
Background:
Azmoth was the son of a minor merchant. His mother had died giving birth to him dispite the efforts of the clerics of Mitra. While he only survived with their help, he forever blamed the church for his mother's death and, by extension, leaving him with his father. His father tried to advance their fortunes but squandered their wealth on women, booze, and bad investments.
As his inheritance was spent, Azmoth turned to other ventures to increase his wealth and power. In his quest for advancement he turned to old books and ways now forbidden. In a moldy tome he found a ritual to summon a minor imp whom indoctrinated him in the ways of power by service to Asmodeus. In order to seal his pack for power and fortune, he was to slay a Priest of Mitra; however, that is where it went wrong.
On the morning of his assassination attempt, a paladin sensed his intend before the poisoned blade reached the Priest's back. Before he could call to his dark power, he was knocked unconscious. Upon waking he was summarily tried and sentenced to prison to await beheading. He imagines every day on his trip to prison choking the life out of the priest and the paladin. Perhaps Asmodeaus will give him a chance to settle the score
