Depends if the person's suffering is their own doing it's their responsibility, but if you can do something about it then i think it depends on your courage or integrity is what i think at least.
Well there are people i know that do that of course everyone is not the same, it is not bad to distrust or discern with people it also depends on the situation, can it really be helped.. can they stand up for themself?
It depends on their will in the end are they strong enough to survive? This is the kind of world we live in, whether one can survive or not is chance. But that doesn't stop people from being compassionate there is alot of people out there alot to choose from, i guess we are lucky we got what we have.
