MP – chazal say the yetzer harah, satan, and malach hamaves are the same. First he gets someone to sin, then he prosecutes the case against him, then he comes and takes his neshamah.
A nice remez for this: the word satan, and “nachash” (representing the original yetzer harah) are the same letters, except one has a “tes”, and one a “ches”. the nachash has a ches, which “faces” down – his job is down here. Then he becomes the satan – the tes faces up, then his job is being mastin in shamayim.
