This is a valuable insight. At some point, even the closest to you are their own individuals. Short of saving their lives from imminent physical danger, at some point, one must leave others "to their fate."
I have come to realize recently that I don't actually have any friends, only dependents.
This is not either-or. There is a friend-dependent spectrum. Also, how you might evaluate this is strongly affected by your own personality. The closer you are to the "dark triad" in the space of personality traits, the more skewed your perceptions will be towards the "dependent" viewpoint.
