We don't need an angry judge to punish wrongdoers. Since anger itself is a mental flaw, it's wrong to punish sins with sin. "What! Shouldn't I be angry with a robber or a poisoner?" No — I'm not angry with myself when I need to drain blood from a wound. I use all kinds of punishment as medicine. You're still in the early stages of going wrong. You make mistakes often, but not serious ones yet. I'll try to fix this with a warning — first in private, then in public. You've gone too far to be saved by words alone. You need to be controlled by shame. For the next person, something stronger is needed — something that will leave a mark. You, sir, will be sent into exile to a remote place.
We do not, therefore, need an angry chastiser to punish the erring and wicked: for since anger is a crime of the mind, it is not right that sins should be punished by sin. "What! am I not to be angry with a robber, or a poisoner?" No: for I am not angry with myself when I bleed myself. I apply all kinds of punishment as remedies. You are as yet only in the first stage of error, and do not go wrong seriously, although you do so often: then I will try to amend you by a reprimand given first in private and then in public. You, again, have gone too far to be restored to virtue by words alone; you must be kept in order by disgrace. For the next, some stronger measure is required, something that he can feel must be branded upon him; you, sir, shall be sent into exile and to a desert place.
