The Detroit News has a number of things on Jack Kevorkian this morning including a long article about him and his current health, a question and answer and an editorial which discusses how previous claims of to not assist in any more suicide weren't actually put into action.
The story and interview paint the picture of lonely, old man who wasted the last 15 years of his life either assisting in suicides and rotting in jail. Maybe Kevorkian thought his actions would spur on the movement to legalize assisted suicide and he would become a martyr for his cause or be released shortly after conviction. Instead, he's been mostly forgotten except for an article here and there every time he gets denied early release. The wasting away of his outside appearance while in jail seems to match the wasting away of his character which occurred years ago.
