The question now is that
1) is it necessary to take loan to gamble when we have no intention to pay back?
He may have the intention to pay back initially if he had won the the bet, but since he has lost the bet and can’t seem to find a better way to pay back, he ended is life like that. Now he’ll now be referred to something else depicting his actions before he killed himself. Don’t borrow money to gamble has been a strong warning for a very long time now to all gamblers, especially those that are addicted.
2) is it necessary to commit suicide if such mistake has been made?
I don’t see anything that can justify committing suicide because of losing bet. The life he has taken is more precious than the money he had used to gamble. I just imagine what could make one be som comfortable ending their own life when they’re face with real time life challenges. I believe it will come and go and that doesn’t stop it from not happening again in the future. That was so stupid of him and shouldn’t have ended is life in such way.
