Only if by “Poorly” you mean “Fantastically”.
So, quick rant, I think Rosa is forgetting something very important here. Her point about the likelihood of this being a murder is correct, but she forgets that, despite the implied size and complexity of Persephone, the chances of all of those things going wrong at once is extremely small. So small, in fact, that the chances of it being orchestrated by other members of the crew are probably the same or higher than it the chances of it being an accident.
Then again, a 50% increase in a tiny risk is still tiny.
