Interpretation and prejudice

See the method of Maran Rabbi Shalom Mashash in the Talmudic Sugiya (Bava Metzia, page 27, page 1), that the evil eye mentioned is not literally, and that it refers to the person himself who will correct his good eye: “And the true and correct interpretation of the words of our sages of blessed memory: ‘Ninety-nine die from the evil eye and one is the death of a person’. It is not literally that they die because they were cast upon by the evil eye, but rather the opposite. They die because they cast the evil eye on others.”” (“Shemesh and Magen”, part 2, page 6)
And so it was explained before him (and Rabbi Shalom Mashash did not see this explanation) by Rabbi Moshe David and Eli of the Italian sages

There is a lesson on this by Rabbi Moshe Elharrar on YouTube that can be listened to

I didn't understand why it was those who cast the evil eye on others who died that improved the situation? And can it really kill?
It seems that what bothered them was not the mysticism of the matter (because in this there is no difference between the one who casts the evil eye and the other) but the death without justification (simply because of the evil eye). But I am troubled by the first question and less so by the second. See R”H Hagiga 5:1: And the solution is that one perishes without trial - such as a person who kills his friend. You see that it is possible to die without justification if the other person chose to kill you.
