Hohoho, I'd erase Lust in a jiffy~ Cause I'm selfish like that. I'm asexual and don't look at others in a sexual way, so I get mighty annoyed when I get looked at in a sexual way. I want to be invisible to others and live my life in comfort, and not get involved in their lust. I see potentially two positive things coming from erasing Lust: Humans phase out of the planet naturally. No need to kill them with a virus, just wait 100 years and they're mostly gone or significantly lessened. Or, humans desperately develop a way to artificially create babies just by donated sperm and egg, and also carry them to term in artificial wombs. You get to erase the undesirable genes and keep the good ones and you get your perfect baby home. Un, if I didn't need to get pregnant, I'd be fine with getting a baby like that. Especially since it won't inherit any of my family's shit genes. Also, if people weren't so preoccupied with sex, wouldn't they develop toward a transcendent species faster?
