That's a big no-no. Gambling with another person's money is a great way to lose that person's trust and friendship.
Only people who are addicted and cannot control them self are those who will borrow money from others as they would have lost theirs already and quite sure they will even lose out the others money and will not have anything to replay later. Thus this spoils the relations as well as not body loves this types of friends or relatives.
Even if we are playing gambling from debts money is such a big fool we never know we will win or not so just play until you have afford to lose that money or better find a job to pay those debts and the loans.Even if we are getting debt from the people is a great mistake as you said it will ruin our trust and relationship between them.
