well, as well know mistakes do happen, and none of us are exempt from that. This mistake was catastrophic in nature, unfortunately, who is responsible for the safe operation of the aircraft? That's a hat we all put on when we decided to join these ranks.
Should the families sue people? That's a debate for politicians, and i don't feel like getting into that. It would have only taken a second to change the outcome of this event, but that didn't happen.
Another note, if there were lighting problems all over the field (which if memory serves correct there were) then not having runway lights on probably wouldn't have been any "big deal" atleast not one worthy of an abort. Also think of how long it would have taken for the pilots to realize that this wasn't the runway, it isn't a "no lights, wrong runway" situation, it'd be a "no lights...hmmmm...wonder why the lights aren't on (V1-VR)" situation.
Best of luck all, fly safe.
