Take a minute to contemplate the world without religeon.
A world without Jewish or Christian morality.
It not too hard to imangine. In north korea, these religeons are forbiden. Dear leader Kim is God. He oversaw the starvation of millions while spending all they had producing nukes. Soviet union under stalin, 20 million. Germany under Hitler, 15 - 20 million? No mercy for the weak. None.
What can be said is that murder is a human condition with or without religeon, yet it becomes unbridled without mercy to curb it, as established in Christian or Jewish faith. Yes, the Muslim "religeon" seems to spawn murder, and seems to be a tenant of that faith, just as Mohammed exercised it. It is no accident that Muslims murder to advance their "religeon". I tend to view the Muslim religeon as a tool of war for men who wish to lord over others. Suicide muder bombing is a case in point. It's a muslim thing. Not Christian or Jewish.
If I had to guess, I would say religeon, as practiced by Christinas and Jews, has saved many more lives than were ever murderd in its name. I dont think this true for the Muslim religeon, and that religeon is not yet done writing its murder record.
