It's called "empathy".
It doesn't require belief in a god.
Then why do you need the "God" piece? Why not simply see yourself in others? Why does that require a "God"?I see God in all because I see no difference between me and them, But I only see no difference between me and them, becuase I see God in them.
I do see myself in them, I see the same God within me, within you!
And some people will believe that their god wants them to hurt others.Some people like hurting themselves, so then they will hurt other people because they'll think they're hurting themselves!
There will always be mentally ill people.
Does that justify belief in a god?
