Interesting questions. You asked four of them. My answer to all four would be the same: No.
If God actually existed then God's behavior in my opinion would be deplorable no differently than any human father acting the same way to his children, would be.
I was taught things like: "You should be thankful to God because "He" is the only reason your heart is still beating; the only reason you're able to take each breath. You're alive only because God wills it to be, every second of your existence. In other words, God created you and gave you life. Be grateful to "Him" because of it. Also, God loves you more than you could ever even know. So...don't question "Him" and don't ask where "He" is. "He's everywhere at all times."
I think of a human father of a large family of children. The father is completely absentee. Actually, to the point that none of his children have even seen him. They've only read about him in books, news, etc and they've only heard stories about their father's accomplishments and his personality. Some of his supporters claim that even though he's absentee, he loves his children more than any other parent could possibly love theirs, because he provides the most very basic needs to his children for them to continue to live (e.g. shelter, clothing, food, etc) and how wonderful a father he is for doing that. Would any absentee human parent be lauded and applauded for fulfilling their obligation and responsibility to provide their children with basic needs for survival and nothing more? Of course not.
Also, Jesus said that he didn't come to earth to abolish the Old Testament, but to uphold it. That means the Old Testament still has worth in "God's eyes". If that's the case, any human who acted in such unpredictable, conflicted, petulant, jealous, hateful, spiteful, manipulative, sadistic, cold hearted and oppressive ways (as God does in the O.T.) would be considered a flat out psycho. Imagine a father telling his grown son to show his love for the father by killing his own completely innocent son (the father's grandson) and then only stopping him at the last second. In human terms and by every measure, that would be considered psychotic.
In some large families there are those kids who are utterly devoted to the father no matter what he does and/or no matter what he doesn't do. Either way, and in every case, the father is regarded as brilliant by those children of his. Then there are those children who do not share the same glowing opinion of the same father (e.g. absentee, etc).
