Judges? How do they become judges?
Elected, or nominated? If they need a minimum years of study, that means they are coming from a fringe of population…
So it could be seen by some as just a justice of class, Judges coming from the bourgeoisie and they will never sentence their own.
So to steal a piece of bread will be heavily punish as it frightens free market economy and the property rights… I push a little bit but…
A jury will balance as some of them will understand why some will steal a bread…

In the Middle Ages, the persons who were judging had to know the accused as they were able to see why he/she did what he/she did.
Nowadays, a jury shouldn’t know the accused.
And both with good reasons
