To put it in short:getting mixed answers from websites as well
Credit card loans are unsecured.
They are high risk, high reward, sort of for lenders.
Unsecured loan's repayment can be refused. (Even by the one who took it.)
The downside is it will cause problems for family members (especially immediate ones) to get a fresh loan as they will also be seen as a liability.
So it's best to pay off keeping future needs or emergencies in mind. (Future is the main reason why people pay off their loans timely, instead of running away with one-time free money)
If one doesn't have anyone next in the family and is thick-skinned. Don't pay back, enjoy that one-time free money. But it will probably be his last loan ever.
