Okay, since lots of differentiation is going on here, here's my take on a more benign interpretation of the Abrahamaics and their conception of divinity:
Although the Biblical myths contain lots and lots of needless cruelty on the part of the deity depicted therein, that is NOT what sets them apart from other theological conceptions of their day and age: most ancient gods were VICIOUS, reflecting the seemingly capricious threat of natural forces that were beyond people's understanding or control. People would randomly die of a fever, or an inflamed appendix, or worms, or a wild animal attack - and people would attribute this to fickle deities who needed to be appeased.
So, when YHVH commands Abraham to cut the throat of his firstborn son, that's not all that unusual - it's what the ancients would have expected from a deity. The unusual twist only comes when God commands his follower to stay the blade, and REJECTS human sacrifices.
It's kindness that sets YHVH apart, even if his depictions still reflect a rather crude understanding of deity that often portrays him in terms of a volatile middle eastern tyrant king of old.
