That's it in a nutshell.
It really isn't that hard. G-d designed us to work together, to take care of one another. After all of creation was complete and declared "very good," G-d declared one thing "not good." "It is not good that man should be alone."
It isn't surprising that when the G-dless asked to be left alone, it is so they can indulge in vice.
Shalom.
