No, because it's an adversarial process where the jury has to choose between the two sides. On each particular, one side wins and the other loses. Their decisions matter. But here's the thing: their decisions, ideally, should be made on the basis of the evidence presented to them, their judgement of the credibility of the witnesses, and the instructions of the judge in how to map the facts as they determine them, to the law as described to them. We shouldn't be okay with a juror voting guilty because of the defendent's race; we shouldn't be okay with someone who says "I'm just going to flip a coin"; I'm not sure it's a bad thing to exclude people who, in the experience of the lawyers trying the case, don't pay attention and invent their own rationales out of whole cloth and make an irrational decision by the standards of the legal reasoning the trial is supposed to provide.
