It is permissible to kill a wicked person
who has done evil things
in the name of deterrence
Jacob Friedman:
This is basically saying that killing people
will make people fear doing bad.
“And all the men of his city shall stone him with stones,
that he die;
so shall you put away the evil from your midst;
and all Israel shall hear, and fear.”
Genesis chapter 9
Mishna, Tractate Sanhedrin, Chapter 7 mishna 1
