So if I die in debt up to my eyeballs, and if I am sole signatory on those debts, I have only hurt my creditors, not my family.
caveats-- if my family was counting on the house and I have an unaffordable mortgage, then yes I have caused them harm. Likewise other irresponsible debts.
-- at the end of the chain, creditors are also people. It is their job to loan money at risk, so their loss is their problem, but this assumes I was dealing in good faith when I took the loan.
