Lol a six year old knows better.
Some do, some don't. Some six year olds do things that wind up causing personal injuries due to their own ignorance of how the world works.
A very spoiled generation will be produced if we intercept any consequences of their choices..
Sure, however parents also have responsibilities and should face consequences for not living up to those responsibilities.
If a parent is fully aware their kid is about to drown in the backyard pool, and they have the ability to save them then they have a responsibility to act. If they don't run out and save the kid, the parent is at least responsible for their neglect, and at the very least partially responsible for the death.
If the parent engineered the situation knowing in advance that it was inevitable that the kid would end up drowning in the pool, then the parent becomes fully responsible for any harm that comes to the kid.
The second paragraph applies to God and creation.
I wonder, do we also blame our parents for every time we disobeyed?
There's a big difference between disobeying your parent, and the parent neglecting their parental duties towards you.
Parents still have a responsibility to prevent you from being put into life threatening situations if they can be reasonably avoided.
If your God is omniscient, then he knew the serpent was trying to deceive Eve, and that they intended to eat the fruit. At any point he could have stepped in (as any good parent has a responsibility to do). Instead he decided to let the situation play out, then take out vengeance on everyone involved.
Why does he get to evade his responsibility?
