Balak

 “Rashi relates that the donkey who rebuked Bilaam died immediately afterwards, so that people would not point to the donkey and (say), “This is the donkey that rebuked Bilaam and left him speechless.” The humiliation of Bilaam by the donkey remaining alive would not have been in keeping with the dictates of k'vod habriyot, human dignity, and so the donkey died.

Had the donkey remained alive, it might have been an opportunity to glorify God’s miraculous powers. People everywhere would have pointed at the donkey as testimony to God’s wonders.  Midrash says that this talking donkey was one of the things created before the creation of the world, ready for just this moment. Yet, so as not to embarrass a man, even a man of such low character as Bilaam, the donkey was not allowed to remain alive.”

The rabbis place a priority value on human dignity, on honoring each individual as a spark of the divine.
