I think helping strangers vs helping family are different. Helping strangers is a very strong form of altruism. You come into their lives, you perform a service or deed and you leave. It could be a recurring thing, like assisting in a soup kitchen or a charity shop but it is both time bounded and emotionally bounded and when you choose to help a stranger the first time or a subsequent time the decision is voluntary. With family though, (as I notice all your descriptions are from) it is neither time bounded nor emotionally constrained since family don't really leave - they're always there, sometimes physically and certainly emotionally. Your first act of kindness to assist might well be voluntary but the second act could well be more out of a sense of obligation than choice and creates an increasingly involuntary burden.
