Lee encourages her mother to leave North Korea. Is this right thing to do?

Lee wanted her mother to share in the freedom she'd found in South Korea.... not to mention the fact she missed her mother. There's no doubt her mother has a better life in the South. Her mother, none-the-less, is having a difficult time adjusting, and at one point..... wanted to return home. In my opinion, Lee was right to want to reunite her family..... in the end, that's all we have.
