If God were a human being or an abstraction, you would be correct in many or most respects. But he isn't - He is the creator. He owns everything and everyone. He gives people free will to accept to reject him. So your premise and mine differ.
He even blesses people with free will he knows are completely incapable of handling it. How compassionate is that? Try handing a loaded S&W M&P to a 5 year old I'm sure people will celebrate your decision as responsible and loving. Hey, the kid has free will and that should be championed above your decision to hand it off them even though it was reckless and malevolent.
The true failure in logic here is the assumption that we're all worthy of the punishment for making the wrong choice coupled with the assumption that we were capable of making the correct choice to begin with.
Looking through the lens of current times your outrage is understandable. But some of your assertions are incorrect. The sacrifice of an animal was done quickly and cleanly. No torture in any sense. It was done to change the hearts of people - to make them understand their sins required repentance. Treatment of women - What may sound terrible from today's perspective was almost certainly a step up for women given the evil of those days. Inter generational curses - I believe this is a misinterpretation of the bible verse. I understand the verse to mean that abused children become abusive parents.
Letting everyone "do their own thing" is a flawed philosophy. Occasionally in these days some little fetid pocket of multi generational incest is uncovered and the people institutionalized for their own good. I know you approve of that sort of interference.
If you are interested I can work to uncovered some more detailed arguments about the issues you raise.
Regarding the sacrifice... It's just really odd, don't you think? Why require death at all? Don't you see how not requiring death for whatever reason is more loving than requiring it? It's barbaric. As for the treatment of women in those days... That was your god making those rules. So, you're saying he's more compassionate towards women's issues today? He no longer endorses killing non-virgins of the husbands you just killed in combat or taking the non-virgin women as your own property?
No need for you to invest time for further answers... I'm content with where I'm at and the views I've formed. Thanks though!
