They look poor, and the father, a convicted felon, would have a hell of a time finding a job. They are involved in crime because--most likely-- stealing is their only way to make a living.
The son looks sad and forlorn and lost, as though he has been neglected, or perhaps abused. Where is his mother? He looks like he needs some motherly love.
They have done bad things, but the extenuating circumstances need to be considered, in my opinion.
Life for people like them can be very hard in bad economic times, and in these times people will resort to desperate measures to survive.
This is rather sad and reminds me of Victorian times when families lost themselves in criminal activities--burglaries, pick-pocketing, prostitution, etc. just to survive.
