If God, (by abrahaic definition) is a creator of life and heaven, has a perfect, unlimited knowledge and morals, and he actually did spoke to Abraham,then yeah, everything he says is moral and should be done. It wouldnt be only illogical not to do it. But you're making some really dumb and outrageous hypothesis to make your point, try to get more intact with reality. And God didnt allow for Abraham to kill his son, so I dont know why you brought this up, when you're trying to make a point that God, religion=evil killing
As for crusaders, they can claim to have done it the name of God and Jesus, and yet their acts still went directly against God's and Jesus's teaching. Christ actually predicted an event simmilar to the Crusades happening and he clearly denounced all the participants in it. Nowhere does it say in the Christian bible that invading and plundering lands are God's word.
You see , the difference between Stalin and crusades is that the Stalin's ideology actually supported his acts while the crusaders didnt. And thats why anti-theism (the strong form of atheism) is billion times worse than any abrahamic religion, and it should be treated as such
First of, anti-theism is as much the extreme form of not believing in a deity as anti-semitism is the strong form of not being jewish. Also, even if you are anti-theist like Christpher Hitchens for example, there is still no moral justification for killing people.
What you admitted in the bold part illustrates the point I'm trying to make. You can have perfectly normal people, and with religious motivations they can commit horribly immoral acts (as in causing carnage and misery) and inside the framework of their faith, it's perfectly moral.
I LOVE ICELAND!
