I get where you're coming from because people and those directly over them will always bear a large portion of the blame and you can only take safety so far.

However, that blame can only go so far as well, because the designers of a thing who overlook or ignore safety loopholes should bear responsibility for their failures. We know some people will always be more susceptible to implicit suggestions than others are and that not everyone has someone who's responsible over them in the first place, so we need to design AIs accordingly.

Think of it like blaming an employee's shift supervisor when an employee dies when the work environment is itself unsafe. Or think of it like only blaming a gun user and not the gun laws. Yes, individual responsibility is a thing, but the system as a whole has a responsibility all it's own.
