In the Babylonian Talmud, the yetzer hara’ (evil impulse/inclination) is also associated with the angel of death and Satan:
אָמַר רֵישׁ לָקִישׁ: הוּא שָׂטָן, הוּא יֵצֶר הָרָע, הוּא מַלְאַךְ הַמָּוֶת.
הוּא שָׂטָן – דִּכְתִיב: ״וַיֵּצֵא הַשָּׂטָן מֵאֵת פְּנֵי ה׳״. הוּא יֵצֶר הָרָע
– כְּתִיב הָתָם: ״רַק רַע כׇּל הַיּוֹם״, וּכְתִיב הָכָא: (״רַק אֶת נַפְשׁוֹ
שְׁמֹר״) [״רַק אֵלָיו אַל תִּשְׁלַח יָדֶךָ״]. הוּא מַלְאַךְ הַמָּוֶת –
דִּכְתִיב: ״(רַק) [אַךְ] אֶת נַפְשׁוֹ שְׁמֹר״ – אַלְמָא בְּדִידֵיהּ קָיְימָא.
Reish Lakish says: Satan, the
evil inclination, and the Angel of Death are one, that is, they are three
aspects of the same essence. He is the Satan who seduces people and then
accuses them, as it is written: “So the Satan went forth from the presence
of the Lord, and smote Job with vile sores” (Job 2:7). He is also the
evil inclination, as it is written there: “The impulse of the
thoughts of his heart was only evil continuously” (Genesis 6:5); and
it is written here: “Only upon himself do not put forth your hand” (Job
1:12). The verbal analogy between the various uses of the word “only” teaches
that the evil inclination is to be identified with the Satan. He is also
the Angel of Death, as it is written: “Only spare his life” (Job 2:6); apparently
Job’s life depends upon him, the Satan, and accordingly the Satan must
also be the Angel of Death. (Bava
Batra 16a)
