tragedy in paradise: a hidden reality

Everything seemed impeccable.
Nature restored; legions of angels with extraordinary intelligence in the service of princes;
cutting-edge social and environmental education; ultra clean and sustainable technology;
hauntingly beautiful children-like their parents; dominion over the entire planet;
perfect government system; wonderfully planned cities; a glorious future; immortals...
And the best: the Good Shepherd living among them...
In short, they missed nothing.

But there was ＂a tree＂ in the path of Adam and Eve...
It wasn’t an ordinary tree, it was special. It was not made to be consumed,
but to warn the couple and their descendants that evil exists;
but it does not need to be evoked.
It was the only restriction...
Meanwhile, myriads of fallen angels desperately yearned to bring about the downfall of the ＂substitutes＂.
And the worst thing is that these evil entities maintained frequent communication with the princes.

What is the formula for seduction?
What fascination is this that surrounded the couple, to the point of convincing them to exchange
Paradise for Hell?
