ISIS also believe in one god.. They love people..As you say
Just because someone claims to "believe in God" does not mean he truly believes in God.
The bible says, '...by their fruits you shall know them.'
Those who truly believe in God will TRULY love His creation.
Which is why statistically speaking... Atheists are better people than christians...
Look at any comparable statistic, and you will see the truth... don't take my word for it, do your own research
I will provide an example... prison populations in USA:
Protestants are 46.5% of the general population, and 35% of the prison population... indicating they are less likely to commit crimes than the average person
Catholics are 21% of the general population, but 39% of the prison population... showing they are twice as likely to commit crimes than the average person
Muslims are 1% of the general population, yet 7% of the prison population!... They are 7x as likely to be criminals!
Mormons are 1.6% of the general population, and only 0.4% of the prison population... indicating they are 1/4th as likely to be criminals
Atheists are 3% of the general population, but only 0.2% of the prison population... showing atheists are 1/15th as likely to be a criminal compared to the average person...
(all this implies getting caught and going to jail, not "committing crimes", but we don't have statistics on people who didn't get arrested)
Statistically speaking...
Muslims are 120 times more likely to be criminals than Atheists
Catholics are 28 times more likely to be criminals than Atheists
Protestants are 11 times more likely to be criminals than Atheists
Even Mormons are 3.7 times more likely to be criminals than Atheists! (Mormons are quite good compared to anyone other than Atheists)
And there you have it... Atheists are the good guys... "by their fruits shall you know them"
