Background
When most see Shish they think he is a big tough simpleton. Although that is partially true, he is actually a trained doctor who used to work for the republic military. He loved being a doctor and saving lives, but because of his terribly clunky hands, most of his patients had complications with the surgeries, and many were maimed or killed by accident. Eventually the republic rid themselves of Shish as he had put dozens of soldiers out of commission. Shish has since found work with the a paramilitary associated with the Jedi trying to save lives, although he ends up taking more lives than he saves.
Motivation
Ambition to become a better/ok doctor
Obligations
Duty - Medical Oath: Shish has made a personal oath to hone his craft and care for injured individuals without causing further harm. His focus is now more on field-care instead of higher risk surgeries.
Addiction: The stress of performing difficult surgeries for the Republic has slowly driven him to alcoholism. He tries to be discreet about it, as he does not want to give others any more reason to doubt his medical prowess.
