No matter what, we all will have to drink, eat and have sex for rest of eternity. Yet no matter how much we eat, we'll always get more hungry. No matter how many seeds we sow, no matter how amazing each experience is, we'll always become horny again. In fact the better it gets, the more we want it.
Its like nothing is meant to last. It almost feels like we hunger for pleasure, yet all pleasure in too much quantity is bad for you. Seems like people go mad trying to quench a never ending thirst, like just talking regular day stuff its a struggle, but we've seen same effects on next level with addicting substances.
I think its why we love the vampire condition so much cause we truly know what its like to be a slave to our hungers. Seems the only salvation is moderation, even then, no animal on this planet can be cured, even the most highly evolved of them still have needs, its robot bodies or bust, even then, we're just swapping needs to lube, oil or whatever the power source is. Please don't get hung up on our creation, but just an analysis of human condition as we know it.
