Answer:
The decision is critical to take. The righteousness of the decision depends on what Marji would like to do in that situation.
Step-by-step explanation:
Marji's parents may have their reasons to not flee Iran like financial problems or native place and so on. But if they think that making Marji live in Iran makes her life better then their decision would be right. But if they have some other reasons, then the decision they took in that situation may not be right.
After all, the decision depends on whether Marji is interested to go live with her aunt in Iran or she would like to stay with her parents.
