I think people need to believe in God and a religion cause otherwise there's nothing to live for, if my death is the end of the story then why prolonged it? if those whose lives are filled with suffering and misery finally believe that it's never gonna get better than this then they'll either kill themselves or go on a killing rampage then kill themselves, why give a damn anyway.
If you don't know deep inside that the good you do will be rewarded then you won't do it or won't do it as often, it has nothing to do with being "naturally good hearted", there's no settings, good -as well as evil- are points of view.
In Bill Maher's documentary he talks to a church group and at the end he tells them "I think being without faith is something that's a luxury, for people who were fortunate enough to have a fortunate life. You go to prison and you hear a guy say: [You know what, buddy? I got nothing but Jesus in here.] I completely understand that. I think not having faith is a luxury", I really agree with that.
So those who are not stupid and still believe in God and religion are those who need it so bad in their lives, just like drugs, and needing it does not promote disrespect from me to either, who the fuck am I to judge?, what do I know? and what have I been through? I think this goes for all over-the-top we-are-so-clever atheists.
Slightly unrelated: One of the songs I always found lyrically fascinating about this subject is Metallica's Cure, even though it's musically weaker than the other stuff on Load; the lyrics really lifts it up for me to top 3 of this album.
The man takes another bullet
He keeps them all within
He must seek no matter how it hurts
So don't fool again
Yeah he thinks the answer is cold and in his hand
He takes his medicine
The man takes another bullet
Yeah he's been fooled again
Uncross your arms
Take and throw 'em to the cure, say...
I do believe
Uncross your arms now
Take 'em too, and say...
I do believe
Yeah, I do believe
The lies tempt her and she follows
Again she lets him in
She must believe to fill the hollow
She's been fooled again
Uncross your arms
Take and throw them to the cure, say...
I do believe
Uncross your arms now
Take 'em too, and say...
I do believe
Oh yeah, I do believe
Betting on the cure
It must get better than this
Betting on the cure
Yeah everyone's gotta have that sickness
'Cause everyone seems to need the cure
Precious cure
Betting on the cure
'Cause it must get better than this
Betting on the cure
Yeah everyone's got to have the sickness
'Cause everyone seems to need the cure
Yeah precious cure
I do believe
Betting on the cure
Yeah, It must get better than this
Need to feel secure
Yeah, it's got to get better than this, this, this
It must get better than this
Betting on the cure
Yeah, Everyone's got to have the sickness
'Cause everyone seems to need the cure
I do believe
I do believe
I do believe
