Well to me, that's just one of those things that work immediately for me. Maybe you're thinking too hard about it thinking that it's a riddle, or a puzzle.
Kong was previously surviving in a harsh dangerous habitat, where it was survival of the fittest. He had to be tough to survive against predators trying to eat each other on a day to day basis.
Then he falls in love.
Love weakens him...makes him soft.
His instincts are impaired, he is weak.
Falling in love with the girl ultimatately kills him in the end.
I suppose it's a bit similar to comparing it to how with some wild animals that are captured, once they've been domesticated they can't be released back into the wild because they haven't got the survival skills needed to just survive in the wild anymore, because they've become soft.
It's just that in this case it's the love for a human woman that has had this sort of weakening effect on Kong.
..and obviously it's a metaphor for life in general.
Love weakens us, takes us over, and consumes us to the detriment of everything else if we're not careful.
And obviously many people can relate to relationships that they've had that were doomed to fail, yet still got hurt by them.
I don't think there's meant to be a clever reason for it's meaning,...I think it is meant as literally as it is said, and as simple as it sounRAB.
I think the meaning "No...it was beauty killed the beast" is as simple as that.
I actually saw the original 1933 'King Kong' film on TV the other day. And when I heard that line again, it just hit me how effective that line actually is.
That was probably one of the best ending lines to any film...ever. And that ending line was probably one of the elements that propelled 'King Kong' to classic status.
