The purpose of the criminal justice system is to pacify the public. The public wants (1) someone to pay (This goes back to early human history in which a crime was seen as bringing a curse on the community. The execution of the "offender" cleansed the community. It is a form of human sacrifice.) and (2) the someone to be the right person.
There are two ways to achieve this goal. The first is to try to identify and convict the right person in every case. This has two disadvantages. First, it is impossible to always be right. Second, it takes a lot of work to get as close as you can. The second is to let everyone believe falsely that the right person was identified and punished. This has the advantage of being much easier. If you give the accused the slightest pretence of having received a fair trial or bully them into accepting a plea bargain then the public will go to the trouble of convincing themselves that justice was done.
You shouldn't confuse the stated goals of any system with its actual goals, especially when the two are oipposed. In theory, the purpose of the welfare system was to metigate and reduce poverty. In fact, the system had every incentive to propagate it. In theory, the legal system exists to arrive at just outcomes. In fact, it exists to arrive at convictions.
A trial is only supposed to be fair enough that the public doesn't ask questions. Anything more is wasteful and counterproductive.
