"Lifespans would be doubled." This is not the same as being immortal. Poor Ru'afo. It's all Picard's fault! I can't believe why I didn't see that. "You exiled us to die slowly!" Maybe he's trying to do the same thing to his parents! Parricide! Oh, okay. So it's alright to be a murderer, as long as it's the Starfleet personnel so that the Federation "never knows what happens here." Killed Admiral Dougherty. But it's all Picard's fault.
