Its called being human and humane. If god exists or nor not has nothing to to with being human and humane.
As the terms "human" and "humane" are being used as a moral measuring stick, then yes - G-d has Everything to do with being humane.
There is NO morality without G-d.
Everything that you or most people today, in the year 2013, consider "moral," comes from G-d and His Torah.
Were christians humane when they wiped out the Cathars, when they started the crusades, or when they instigated the inquisition.
Absolutely NOT. The Crusaders were largely immoral - as was testified to by St. Bernard at the time.
Were muslims humane when they converted people to islam under threat of death
This is a fiction. Islam did NOT practice "convert or die" when they conquered the Middle East, North Africa and Asia. This is a modern barbarism which has corrupted Islam altogether.
(which christians also did)
Only after Christianity was co-opted by Rome.
When the State takes over and dictates your morals, then bad things happen.
or when "the sword of islam" eliminated 5% of the worlds population?
Interesting. Never heard of this one. Do you have data to share?
Were jews humane when they followed the "word of god" and wiped out cities and tribes in the old testament.
Absolutely. Yes. When G-d tells you to do something, it is by definition, humane.
If there is one thing that is common to all abrahamic religions, it is their inhumanity to their fellow humans. Their god is not humane only conspicuously absent from this world.
Utter nonsense.
Because your opinion of what is "humane" apparently differs from G-d, you consider those that disagree with your purely subjective opinion "inhumane."
This is true of most despots and tyrants of the world.
Anyone who disagrees with THEIR opinion is, by definition, "inhumane."
