>What I did ask for is evidence that "Amazon literally killed their employee"

employees died, you agreed it was Amazon's fault, if it is Amazon's fault that an employee died then Amazon literally killed that employee. Notice it was never said Amazon is legally culpable for the deaths of employees which has a different meaning in English than 'literally killed'.

>this is just a case of mis-using the word "literally" for dramatic effect.

I must admit I find the grammatical high-horseplay evinced by the last bit rather weird, for the reasons I have outlined.
