Right, because once I'm zapped onto a spaceship full of murdering psychopaths I'm left with so many options for how to proceed.

And anyway, just because that's what you've seen, it doesn't mean it's without exception. I'm not saying these guys aren't terrible, or that it's wrong to condemn the crimes they've committed. I'm just saying...if their leadership falls apart, isn't that enough? Without a head, the arms and legs are useless. So cut off the head, sure, but you don't need to hack the body to pieces.
