Same idea, but if a pedestrian is jaywalking across a street, technically illegal and it's not a safe move - but is struck by a car - the car is still at fault. As a driver you are still in charge of driving a 2-5 thousand pound hunk of steel and you accept that risk when you get behind the wheel. So I think logically, what the person was doing was not the smartest - but that doesn't mean they deserved death for it - you are responsible.

Think about it this way - if you hadn't been there driving would they have been fine? If so, you caused it, you're at fault.

Same applies to rape and dressing provocatively. It's an irrelevant argument because it puts blame on the victim, when no matter what they do they don't deserve that outcome. The blame is on the person who caused it in the first place.

Are you saying the driver is wearing the seatbelt, the passenger(s) aren't?

And how does the death result? Is it because of an accident? Are they messing/moving around in the car? Are they legally allowed to not be wearing a seatbelt in the vehicle?

There's too many undefined variables I think for anyone to give you a solid answer.

According to this page, you could attempt to argue "lack of causation" if there was no connection between you not wearing a seat belt and your passenger getting killed.

It still falls back onto the driver, as they chose to start driving without everyone buckled in.

As I understand it, getting someone killed through negligence of any kind is manslaughter.

So I'd say yes.
