God is above people's lives and deaths, he created the concept of both.

Since you're so keen on your gnostic "yhwh is the devil" goggles, start with the flood, or Sodom: more death.
Even in the Moses story, all the firstborns of Egypt? Some were surely good kids!

God's making of humanity is certainly mysterious, at least as mysterious as if he were an explosion and monkeys.

Makes sense that he would be serious about the ten commandments though.
People who don't take regular breaks from their daily jobs become turbo insane workoholics and if the hebrews had done that, the world would be way way worse than it is now for that guy's death.

Imagine the kind of man it takes to see the creator of the world part the sea, destroy the biggest empire on earth in a day, hear him say "take the day off" and decide "eh what ever I'll just not take the day off, just to show him who's in charge"
Not the best kind of man for sure, and frankly I'm glad he didn't become a nation.

As for the deaths of all those killed by god's actions or exhortations, you have to see something here:

we can play a video game in which, in order to make the game unfold the way we want it, much video game "death" occurs.
This is not actual murder, even though we didn't create the computer (and in most cases didn't even program the game).

To God, we're not all that: he can make an entire new world like you'd make a pie, and if it doesn't taste or look like the pie you want, you can throw it in the bin and make a better one.
If you kill some guy you'd be insane scumbag & c, but if you throw your #ty pie in the bin, or a small part of an apple on it that looks like it may be unfit for the pie? Basic pie-making

Judging god isn't even as smart as denying god: if you think there is a creator, what ever he does is his prerogative entirely and you have no more right to judge it than the pawn on your chessboard can tell you to move the queen to b6 or you're a scumbag.
So the gnostic workaround is to say "oh but "yhwh" isn't the creator."
You either receive the story or you don't: yhwh is the god of Moses who is the god of Jacob four generations earlier, and is the god of Abraham who is the god of Adam who is the creator.

human emotions do not apply to god in any way, not taking his guidelines seriously results in much unnecessary grief, believing the serpent is what made Adam's kids go through all this nonsense to begin with.

"yeah let's believe the serpent again, surely this time he's on our side"

well.. nope

Didn't work when he said science of good and evil would make us gods
won't work when he says he's god and god is the serpent, either
