alot of this is just arguing semantics. human beings are empathetic creatures who are for the most part instictively driven to do good for the people they see as being in their group. their attitudes and often their morals are shaped by the other people they're connected to either conciously or subconciousely.
Our egos may tell us that we don't need anyone and that our attitudes are rational, but deep down our gut knows better. And thats why we are all scared of being abandoned by our society. we're afraid of scorn and of being alone, and thats represented by jail or homelessnes.
