A lifeguard saves someone while drowning person. A nurse, a police, an ordinary person does so.
even a murderer tries to save a drowning person in case of a disaster. Because he knows if he saves him, so the victim may help himself when he need. Shortly, a murderer helps others in case of disaster to increase his own living possiblity.
So that, in disasters everybody even gangsters help others.
Maybe there is so so so rarely exceptions, but this does not affect the general rule. It maybe happened with a very very low possiblity, but in my opinion son of orospu is saying lie about gangsters. This is my though depends on human psicology may be wrong with a very low possiblity.
I don't now why son of orospu say this but either he is trying to attract attention himself or he has been mentally depressed because of huricane.
