The twins have no desire to help themselves out of the situation they are in, a situation which is partly their own making.
Fair enough, when Linda died it was tragic and the way Tom changed didn't help them, but at no point did they try and take control of their own lives (although to an extent Jason has now he's got a relationship going and a small kid to help look after). They carried on down the same path as their brother Paul (not shown in the documentary, but mentioned by Tom) of petty crime years after Linda's death and being taken out of their home.
Neither of them have a job, or anything going for them, apart from the community service (although now they are allegedly back in prison, even that is gone).
They showed no remorse about the compensation money going so quickly. They seemed quite proud to be able to reel off to the camera everything they have spent it on.
People have tried to help them to the best of their abilities, with the possible exception of Tom, but the twins haven't tried to do anything to make it easier on anyone else.
I'm glad I have no contact with that side of the family any more.
