To me this is not an ethical question.

Yes the guy has cancer and that's sad but why is that now your responsibility?
Or, him having cancer should not cost you any money.

And were is his family in all of this? Doesn't he have a brother or someone else that can help him out?

If I was the one with cancer I wouldn't be trying to take advantage of a stranger in my last days.
