I would argue that you are placing misnamed choices. Both are different flavours of Justice: A) Retributive Justice: Put them in Jail for long time. B) Rehabilitative Justice: Put them in medical care for an year till their gambling addiction is cured. Then they are free to integrate back into society. All else being equal, I would absolutely prefer B over A. However, there is also a third option C, which can be combined with either A or B: C) Restorative Justice: Require them to do a certain type and amount of work for you or for the state to make up for an agreed amount of your lost money and moral damages. Give me a mix of B and C any day, and throw A down the drain (in the sense of prison purely as punishment, I have nothing against using prison to protect society from certain criminals).
