No,no and again no. It could lose you your job with the charity that you have at the moment and open up a great cupboard of demands on you for money, help, dispute resolution and other troubles that cannot be forseen.
I worked for Age Concern (as was) for many years as a volunteer Home Visitor and we constantly had it ground into us that we should not get over involved with our client's lives. On several occasions, I had to walk away, having done all I could, knowing that having done everything I could and passed it on to another body who should take responsibilty but wouldn't. That must be the end of the case for me.
The fact that you have posted about this in GN shows that you too are not sure whether you should do any thing.
Whatever you decide to do. never,never, never, give money, give in kind and small quantities, so that it cannot be sold on.
