Background
The Specifics of Oden's early life were not important enough to be recorded into the annals of history. In fact, very few records his birth exist; those within the Jedi Archives are, perhaps, the most reliable. There are rumors of a prophecy, an angry myrmitrix taking control of her hive, only to be beset by Oden's father, Dessaro. A war of two years, ultimately ending in the involvement of Jedi Order and the induction of Oden into their ranks.
But that very same war had left the child's perceptions of the universe, his philosophy, deeply afflicted. None though that Oden was evil, simply... Different. Uncanny, almost. He developed an obsession with justice, upholding it, defending it and, eventually, creating it. As time progressed, he became more and more disconnected from the order's own laws, instead believing that it was his birthright to forge his own laws, his own path.
The Clone Wars, unfortunately, further cemented this idea in his mind. Every conflict, every decision brought him further and further away from the Jedi Code and closer towards his own. Eventually, he'd decide against the active hypocrisy of letting himself be defined by a code he had no part in writing.
He openly abandoned the Jedi Order, casting himself out into the outer rim where he would go into hiding from both the Separatists and the Republic. In this time of quiet, he perfected his own mind. Oden traveled planets that meant something to him, eventually returning to Li-Toran as the Empire emerged and the Order faded into obscurity. The Hives would protect him.
What he found there is a mystery to all looking upon his tale. Li-Toran was the nexus of his emotions, where his turmoil had all began. Perhaps he sought peace, strength... But instead, he emerged with a bloody red blade, the surname Dessaro and rumors of a hive turned graveyard. It wasn't long after these reports that the Inquisitors came, and it wouldn't be long after they came that Oden Dessaro was among their ranks.

Oath - Ward
Morality
Justice is an integral part of who Oden Dessaro is, today. It is the sole reason he abandoned the Jedi Order, now he defines himself by the Edicts, the Code, that he has created. Justice is the essential aspect of his morality. His personality. His very being.
That very same Justice, however, sees the inquisitor acting as judge, jury and executioner more often than not. This obsessive pursuit has made him a Cold-blood killer, incapable of even the most basic displays of affection, or care. All that matters is Justice.
