I'd say the death penalty is warranted here. Anyone that sick doesn't deserve to live, period. Maybe mitigate her sentence to life in prison if, and only if, she provides the authorities with all her client's info because those sick fuckers need to be culled from the gene pool on general principle as well. People that fucked up at the genetic level can't be rehabilitated and are simply too dangerous to be left in society at large. I've always been pro-death penalty, but this sort of shit makes me want to extend it to crimes and psychopaths like this.
