See this here is just nonsense.
The players take the box and twist/subvert it to their own perversions, the builder could have put safeguards in (which they kind of did with modes... sorta) but the players have to take responsibility for their own actions.
Just because you can do something doesnt mean you have to or should do something, those are the players choice not the designer.
If the designer wanted to they could have made every player kill end up with both ships being blown up but in this case I think they probably thought people would not be such crass smegheads.
That was their folly. But to excuse player actions just because its possible is just plain stupid.
We all act stupid from time to time.
