Just my interpretation but still
>The fruit of realizing good and evil
Before eating from the fruit they accepted the things as they were. They lived in a blissfull state, because they didnt categorised events in 'good' and 'bad'. Thats what I think the 'garden Eden' (Paradise) is. They didnt try to avoid the bad things or purchased the good things, they just accepted it and lived with the events as they were. 
After eating from the fruit Adam and Eve could JUDGE if Event/Person/Behaviour/whatever is good oder evil. 
If you start judging you try to avoid the bad things and move towards the good things.
This was forbidden knowledge because only 'god' can judge if sth is really good or bad, especially in the long run of things.
So after Adam and Eve could judge the world they no longer lived in garden Eden. And so the human struggle for 'better/faster/mightier' started.

for example:
Before the fruit (judging) 'Adam' could see a venomus snake. Out of curiosity he starts petting it and the snake bites him (bad). He runs in his town and 'Eve' sees the bite, sucks the poison out, and watches over him till he feels better. The two fell in love and 'Adam' met his soulmate. (Bad thing turns good)

With the knowledge of good and evil, Adam sees the snake, walks in a big circle around it and never gets bitten. He knows snake bite = bad. He never met his soulmate and became an incel.

Also funny that the first story in the bible tells us to avoid judgement, yet the church people are the quickest ones to judge others..
