Musar על ברכות 33:6

The root of piety is what our sages, of blessed memory, stated: "Fortunate is the man whose toil is in the Torah and gives gratification to his Maker" (Berachot 17a).

You shall be men of holy bearing to Me, and; you must not eat flesh torn by beasts in the field" (22,30). The Talmud Berachot 17 states in the name of Rabbi Yochanan סוף אדם למות, וסוף בהמה לשחיטה, והכול למיתה הם עומדים. "Man's destination is to die, the domestic beast's destiny is to be slaughtered, all are ultimately destined for death." Why is the kind of death the beast is slated for described as "slaughter?" Also, why does the statement repeat that "all are ultimately slated to die?"
