I always had trouble wrapping my head around the Ransom thing.
I tried to get my Dad to explain it, and he essentially described it like so...
...a "perfect" man - Jesus - had to willingly accept the sentence for a capital offense against Jehovah that he didn't commit to correct the cosmic imbalance (somehow) caused by a "perfect" man - Adam - being justifiably sentenced for a similar capital offense (which, in turn, had also created some kind of nebulous genetic flaw which resulted in "imperfection" *).
When I asked why Jehovah didn't simply forgive Adam for his sin, I was told that...
a) ...Adam wasn't actually repentant, and besides...
b) ...when you sin in a "perfect" state, forgiveness isn't possible.
Ultimately, though, all this explanation did was make me scratch my head until I - ultimately - gave up on fully grasping it, and instead become somewhat fixated on "perfection"...
...to the point where, in fact, I thought that all my various unhappinesses were actually the result of my own "imperfections", i.e., inherent flaws.
In fact, looking back, I think that was a major component of why I stayed in as long as I did...
...the WT's "New System" ostensibly promised "eternal life", but "perfection" was my specific carrot, because I thought that, besides being more physically attractive, it also meant never being wrong or making mistakes (understandable when everybody around you says, "oh well, we're all imperfect, we make mistakes" whenever you screw up, which I nevertheless found hugely embarrassing and hated), and therefore - theoretically - never feeling bad about myself again**.
Seriously.
It's funny now, but it actually felt like a huge weight was lifted off my shoulders when - shortly before my fade - I realized that the vast majority of JWs each defined "perfection" a little differently from the next...
...i.e. notions of "perfection" were so extremely subjective that - ultimately - there's really no such thing...
...and, therefore, aspiring towards it was a total fucking waste of time and energy.
...
*On a related note, this is the primary reason for the WTS's rejection of evolution... their cosmology simply doesn't work if Adam isn't a literal historical figure as he's presented in Genesis...
...but...
...I now actually wonder if said cosmology was tweaked by WT "theologians" this way specifically because they found evolution so objectionable.
**I also suspected people got off on using said wrongness and mistakes as a pretext to counsel criticize pick on me, and if/when I became "perfect", they would be silenced forever, much to their chagrin and my immense satisfaction.
Yes, I freely admit I had a massive chip on my shoulder.
