Reply To: Chidushim on Daf Yomi Shabbos 30

שבת צג,ב

Rashi on Rabbi Shimon Potar says that removing a dead person is considered a מלאכה שאינה צריכה לגופה, work don’t done for its own sake, because he is using the melachah away from himself and he rather would not require it in the first place. Tosfas on the next middle of the page with the starting asks many questions on Rashi. Why opening up a wound to make it breathe is chayev, he would rather not have the wound. The Meginas Shlomo answers that there he wants the opening to stay even after it is healed in order that it should not return wheras the dead, once it left, he wants it not to return. So, Tosfas there says he is patur because he is not doing it in the same fashion done in the mishkan. We find later on (103,1) where the gemorah says that when one plows in someone else’s field is not a פסיק רישא as he does not care about it. Tosfas says that it is a again work not done for its own sake. Similar thing we find in Sukkah (33,2) the gemora says that he has another hashana and trherefore he is not fixing when removing the fruits. The Sefer Kapas Temorim there has a long discussion about the difference between a pesik reisha and work done not for its own sake. He asks that according to tosfas above the example we give for a pesik reishe, kill a chicken to play with the head so you don’t want to kill it to die but play with it. Isn’t this the same as you dig a hole for the ground sake and not for its own sake? He says that it only demonstrates the fact that it got killed without his intention to die but it would really be patur. The problem is that that the hole also happens automatically? In the mishkan they would make a hole for its own use and not for the ground. The Rambam holds that it is chayev would learn like Rashi in work done not for its own sake.
