This legal phrase came to my attention this afternoon: https://en.wikipedia.org/wiki/Fiat_justitia_ruat_caelum
There was a time in my life when I would heartily endorse this statement. What do you think Epicurus would say about it?
Epicurean, or not?
There's an exchange in a A Few Days in Athens where the subject of criminal rehabilitation comes up. Metrodorus (having to mind the memory of the scandalous behavior of his brother Timocrates) takes the position that some crimes are so beyond the pale that the guilty are irredeemable. Epicurus seems to take the position that redemption is always possible, and mercy is to be favored if there's a chance of atonement. Not canon, of course, but not bad.
For myself, I rather like that scene from Robert Bolt's play A Man for All Seasons that Christopher Hitchens was fond of citing in defense of free expression.
It's worth noting that for Epicurus justice existed not naturally but by convention. If men convened in order to criminalize impiety (as of course they generally do, when given half a chance), the teachings of Epicurus would themselves be the act of a reprobate. I'm aware that I haven't really answered your question...
(1) So you have read A Few Days In Athens! Excellent!
(2) That is LOL funny in the line "then let God arrest him!"
(3) I do think your last comment re "convention" is the right direction to the answer 
Hiram's edition, actually. My Amazon review is dated January 2018. (I've just found it again myself. My review reads as a bit sappy to me now, but the emotion was utterly genuine.)
More disconnected brain ramblings; there's a story related by the great French essayist Montaigne about the justice system of the time. An innocent man was condemned to die; when the actual criminals were found out and confessed, the judges met to discuss this first man's fate. They decided that he must still be executed, because "it was better to execute an innocent man than endanger respect for law." (Paraphrase by William Hazlitt).
I would say it is profoundly anti-Epicurean. We should always take into account what the consequences will be.
