Your methodology of flipping phrases is not making sense.
It's ok to flip this verse because it's an equation. Flipping this verse doesn't make sense to you because you've interjected knowledge on the Jesus side and left it off the Adam side.
Perhaps you would like to explain the meaning of Ro 5:18, without doing violence to the text:
My pleasure, but first, your way:
"the result of one trespass was condemnation for all men."
Therefore as by the offence of
one judgment came upon
all men to condemnation
You believe because Adam sinned every human being is damned...period.
EVEN SO (<---Here's the equal half)
by the righteousness of
one the free gift came upon
all men unto justification of life.
I have done nothing to this one verse except use your own logic...therefore, you believe because of Jesus sacrifice, every human being is justified...period.
Now, my way:
Therefore as by the offence of one judgment came upon all men to condemnation; even so by the righteousness of one the free gift came upon all men unto justification of life.
Hmm, something is wrong with this equation, because not everyone receives justification simply because Jesus sacrificed. Oh....here's the problem solver:
Wherefore, as by one man sin entered into the world, and death by sin; and so death passed upon all men, for that
all have sinned:
I better check my math:
They hold the truth in unrighteousness...they clearly see and understand so are without excuse...they knew about God but didn't glorify Him and on and on....
The equation is now balanced.
Agree or disagree?
