Discretionary justice or according to law.

WHAT IS JUSTICE?
Number 1 meaning of justice is "The fair and proper administration of Law" (Blacks Law Dictionary 9th Edition.)
Example: a first offender was brought to court, on the process became afraid and tried to run away from court. He was arraigned for trying to evade justice and was sentenced to seven years imprisonment.
Another was brought to court and he too was a first time offender, he became afraid of what is before him and tried to escape and was caught. On arraignment he was sentence to six weeks imprisonment and a community service to wash public toilet.
Can you reason on the type of justice playing out here? whats your disposition on these two judgments.?
