Well it is kind of you nonetheless. I've heard of evil people spitting on these poor souls and kicking them as they sit there. The man who makes a dog out of sand had his sculpture trodden on and ruined by some louts a while back. It's so sad.
As I get older I find I feel suffering more and more, and I have to admit I try to help in order to salve my conscience a bit. My husband's the same; we both just can't bear it, and it cuts us up to see these things.
I agree that almost anyone can end up in this situation through bad luck, ill health, mental health problems and so on. I never ever judge; it could indeed be me at a later date, who knows?
