Bava Kamma 44 - Shabbat December 16, 4 Tevet

Why was it necessary for the verses in the Torah to specify that an animal is killed even if it killed a minor? Is this the case also if it was a shor tam? If an animal kills without intent to kill or with intent to kill an animal and killed a person and other such cases, the animal is not killed, but Rav and Shmuel have a debate about whether or not the ransom needs to be paid. The Gemara brings in the opinion of Rabbi Shimon who holds that even if a person tried to kill someone but killed someone else instead, he is not punished by death. He would hold the same to be true for an animal who kills. And this would disagree with the tana of our mishna. From where in the Torah is each opinion derived? Once an animal is sentenced to death, it is forbidden to benefit from it. Therefore, if one sells it, the sale is invalid and likewise if one dedicates it to the Temple, it is not sacred and if one slaughters it, the meat is forbidden. However, before the sentence, all those acts are valid.
