For a hanged person is a curse to G-d (Deut. 21:23)
It is a degradation of the Divine King in whose image man is created...
This is analogous to a case of two
identical twin brothers. One became king, while the other was arrested for
robbery and hanged. Whoever saw him, would say, "The king is hanging!"
(Talmud, Sanhedrin 46b)
When you reap your harvest... and
forget a sheaf in the field, do not go back to fetch it; it shall be for
the stranger, for the fatherless and for the widow ( 24:19)
Certain opportunities and potentials are so lofty, that they
cannot be accessed by the conscious self; they can only come about "by
mistake." An example of this is the mitzvah of shikchah
, which can
only be fulfilled by forgetting.
(The Chassidic Masters)
