The reality is that large numbers of people in prison come from chaotic family backgrounds and/or may be drug addicts and/or suffer from mental illness. To characterise people like that as guilty of making their innocent families victims is unspeakably cruel and is revealing of the person making that accusation of never having lived in the real world. I worked in the East End of London, then Walthamstow, for many years and I came across hundreds of children who lived in busted families, in poverty, in neglect, many with parents or siblings who were addicts or criminals themselves. It's a tribute to the resilience of children that most in those circumstances end up as decent citizens, but, of course, plenty don't. It behoves us to not condemn outright the ones who turn out "wrong" without showing at least some understanding. Dangerous people will always need to be locked up, but, with the exception of a few of the hardest of hard cases, most people can be helped to become better people. Involved in doing that is allowing them easy contact with their loved ones. Not 24/7 but good opportunities and without the need for long-distance travel.
