No, they're the same thing from a risk management perspective. As a defender, you do not (or at least should not) care about motivations. Seatbelts protect against genuine mistakes (by you or others), mechanical failures, road rage, etc.

There's a long funnel of all the things that could happen, probability of each, and total resulting probability. That's no different for being in a car wreck or being shot at.

Now, on a moral level, sure, malice is different from negligence is different from coincidence.

The motivation is not the important part. Sentience is. This person is playing a chess match trying to defeat you.

Consider biology. Cancer is a hard problem to solve, but it's not scheming against you with an intelligence. What about someone in a lab engineering bioweapons?
