Study 3a included a survey of 130 U.S. residents (64 liberals, 36 conservatives, 31 moderates), each of whom was given 100 “moral units”.
Participants were asked to distribute these units according to their capacity to empathize with and behave morally toward the categories featured in 16 concentric circles.

If you want to put these 100 units in the 16th circle then you wouldn't have any left to allocate to your family(, even if they'd be conceptually be included by selecting outer circles).
Here are the 16 circles, from close to increasingly distant :
(1) all of your immediate family,
(2) all of your extended family,
(3) all of your closest friends,
(4) all of your friends (including distant ones),
(5) all of your acquaintances,
(6) all people you have ever met,
(7) all people in your country,
(8) all people on your continent,
(9) all people on all continents,
(10) all mammals,
(11) all amphibians, reptiles, mammals, fish, and birds,
(12) all animals on earth including paramecia and amoebae,
(13) all animals in the universe, including alien lifeforms,
(14) all living things in the universe including plants and trees,
(15) all natural things in the universe including inert entities such as rocks,
(16) all things in existence.

Like most of us, psychedelics made me realize/experience that we're all one.
Christianity also helped me(, among many other things,) to realize how much of a sinner i am, so my mindset should be to live a life entirely devoted to make up for my past sins, at least as much as i can.

Now our modern civilization has erected selfishness as a pillar, as logical, as a human nature that shouldn't be changed, with our hedonistic&materialist goals, and we will( continue to) bear the expected consequences. There's a cynical machiavelism behind most selfish/nationalist decisions, instead of an insistance on researching/discovering/spreading publicly the most moral solution we could find, after important efforts mobilizing a sincerely concerned nation.
There wouldn't be any need for constitutions or laws if everyone was christian, always preoccupied with 'the common good'/'being the most virtuous'/'all of Us/us instead of them', in all situations. Of course perfection is usually unattainable, but it doesn't mean that there's any other aim worth walking towards.
