You can stop imagining now because you can’t get the perfect answer to that same way we have different faces, so are our minds and ways of thinking. If you ask me, I will say that we all have that greed inside of us, but how we control it differs.
The gambler knows what he wants, and we are busy attacking him today because the game did not end well based on how he planned it. If he had rejected the cashout and luckily the game ended as expected, all this could have not been a topic of discussion. It’s all about risking for the greater reward, but that kind of risk should have been what he can afford and not what he will later regret.
What do you expect? Everyone have the chance to talk because it went bad for him which the case would have been different if the case went a whole different way. I have seen so many people risk it all by not cashing out and it favoured them although sometimes we have to be wiser if the option are good enough but die hard gambler would say no quitting till the game is over which to others is pure stupidity and greed.
Actually, it all comes back to each individual for the matter of decision, meaning a gambler is free to decide whether they will cash out the amount of winnings that are already in front of their eyes, or choose to continue with the hope that the last game will be in accordance with their predictions, everyone is free to choose but the problem is not all of them can really be responsible for their choices, and that is why responsibility is very important.
The point is if for example you are unable to accept the fact of defeat when it turns out that the last game is not as you expected then clearly cashing out from the start is the best option you can choose, and I think this is not a matter of a true gambler or not but about how smart you are in taking advantage of every opportunity in order to enjoy the results of luck at that time.
