I understand what you are saying but I believe that in the end, regardless of original intent, they do and become exactly what I said. So you might say, “It was my fault I died” as a roundabout way of saying “I could have saved myself” but after a time you start to forget that the actual and original fault lies with the person who aggressed you. And moreoever, the one who aggressed is so often pushing that narrative of your guilt and their innocence.
I also need to point out that fault and blame can be shared. For example, if I go around the forum claiming I am ungankable, and then someone ganks me, I would say I share blame in my own ganking for basically inciting it. But fact remains the ganker is still far from innocent. Ganking people for running their mouth is no better reason than most other reasons given for it. (And to be clear its not ganking I have trouble with as much as I have a problem with the lack of clarity surrounding the practice).
