Why was ???? scared to kill ??? (Rashi says that ???? refers to killing others) — there is a ??? of ??? ????? ???? ?????, that if one comes to kill you, can kill him first?
One cannot answer that one is only allowed to kill a ???? if it is impossible to save him through disabling him somehow [and therefore ???? was scared that he would kill even if he wouldn’t need to], because the ???? and the ???”? hold that this law applies only to a bystander; the victim himself is permitted to kill the ???? even if it is possible through other means to save himself?
There are those who answer that ??? came to kill ????s family, not ???? himself (because ??? promised not to kill ???? while ???? was still alive), and therefore he didn’t have the ???? of killing; he was considered like a bystander, and therefore was not permitted to kill without trying to disable first.
(There are those who explain this ??? of the ???? because he is ???? (confused, not thinking straight), which comes under the category of ????. I don’t understand this, because the ???? of ???? does not apply to the 3 Cardinal Sins of ????? ???, ????? ???? ?????? ?????, which are ????? ??? ?????? One could answer that the ???? does not create a ???? to kill, but rather changes the circumstances so that it isn’t ???? ?????? ???? ??????.)
