After what he did, I am sure that there is some flaw in Arons background. When a Jew is missing one of the three defining traits of Yid- Bayshunus, Rachmunus… You have to suspect that maybe he is not a Yid after all.
The Gemora talks about a Kohen who described his portion of a korban “as small as a lizard”. Because he refenced an unkosher animal his background was checked and it turned out problamatic.
I am sure that if his background was throughly checked we will find that Aron isn’t qualified to be called a kosher Jew.
No I absolutely do not have mercy on him!
Its like those judges who let the Lockerberry bomber free because of misplaced mercy!
