He certainly was an interesting person. It was always amazing the degree to which law enforcement prosecuted his hacking and cracking, when it seems like much more impactful crimes involving computers go uninvestigated. Plenty of people are hounded by threats of violence into leaving their jobs and homes, that seems far more impactful than Mitnick's crimes.
And FYI, while he died unexpectedly young, a 57-year-old man in the US has only a 50% chance of living to see their child reach 23 years of age. I, personally, wouldn't feel comfortable risking leaving a child with a likelihood of dealing with my death at that relatively young age.
