Don’t blame the messenger. Maybe that is not HOW you prefer to view God, but the words are clear: (Numbers 14:18, or Exodus 34:7 or Exodus 20:5) “I will visit the iniquities of the fathers”… There is no reason to accept your interpretation. The words are clear: “I will visit”… Not something like… “if you do this, it will carry these consequences unto your children”.
I think you have misunderstood the meaning. Consequences of sin do persist, sometimes generationally, but to the progeny, they are only “visitors” that do not remain. Progeny are not bound to the sins or the punishments of their parents.
Code:
The words of the Bible are clear: "cursing the world, the ground, in pain you will deliver your children... etc..."
Actually the words of the Bible are a lot more clear than you seem to remember.

Women already had pain in childbirth:
Genesis 3:16New American Standard Bible (NASB)
16 To the woman He said,
“I will greatly multiply
Your pain [a]in childbirth,
In pain you will bring forth children;
Yet your desire will be for your husband,
And he will rule over you.”
And there is no “cursing the world”, but rather, a cursing of Adam’s relationship with nature.
17 Then to Adam He said, “Because you have listened to the voice of your wife, and have eaten from the tree about which I commanded you, saying, ‘You shall not eat from it’;
Cursed is the ground because of you;
In [f]toil you will eat of it
All the days of your life.
18 “Both thorns and thistles it shall grow for you;
And you will eat the [g]plants of the field;
19 By the sweat of your face
You will eat bread,
Till you return to the ground,
Because from it you were taken;
For you are dust,
And to dust you shall return.”
I don’t know who you are, to decide this is not a “natural consequence”, since you were not there at the time of creation. We are God’s creatures, and He can produce any consequence He finds fitting.
Don’t try to “whitewash” God, it does not work.
Actually, the consequences of original sin are not whitewashed at all. They are quite serious. In fact, you seem to want to “blackwhash” God as punitive, vengeful, and unloving.
It does not work.
