I think my point was distinct from naming this idea (Death of the Author). It wasn't about guilt it was about consequences and those are distinct things.
Also, AIUI Death of the Author is not about whether their beliefs mattered to understand the intended meaning, but instead whether "intended meaning" is even a thing anyway. No need to understand it if it doesn't exist. I prefer in other contexts not to try to guess intentions when I can instead look at the effects and it seems to me our law and practice agree.
Notice for example that while proving attempted murder requires that you wanted the victim to die, murder does not. The fact that they are dead satisfies this aspect of the crime, you aren't innocent of murder just because you didn't intend that the victim would die.

You might be; from the UK's Crown Prosecution Service guidance website[1]: "Involuntary Manslaughter. Where an unlawful killing is done without an intention to kill or to cause grievous bodily harm, the suspect is to be charged with manslaughter not murder.". From Wikipedia[2]: "In English law, manslaughter is a less serious offence than murder."
