Halacha has a strong tradition of "minimizing a transgression" when doing something forbidden, for example taking the shortest route possible when driving on the Sabbath.
Applying the same logic, suppose you were to purchase a cut of non-kosher slaughtered beef that would be kosher had it been properly slaughteted, and you soaked it, salted it and washed it as we are commanded to do, and ate it yourself (without offering it to anyone else). It would, of course, still be treif.
But would you be "minimizing your transgression" of eating non-kosher beef vs. eating that same treif piece of meat without having kashered it, or commiting another transgression entirely?
