The Answer: hit men and mercenary killers and prison staff who administer lethal injections.
The Question: what are jobs I seriously doubt I could do without completely losing my shit.
Bear with me here because I haven't quite wrapped my head around this concept, given that I think it's pertinent to interpersonal engagement on any given day with any given person and also bleeds thickly into my perspective on politics, evolution, world peace, and all the heavy stuff people get crazy uptight about.
Biologically, I don't know that I value human life any more than the life of the mosquito that's now smeared across my forearm. This is obscenely oversimplified, but seems to me that we can look at each individual, within any given life context, as either an asset or a liability. Helpful or hurtful. Beneficial or destructive. Benign or malignant.
Emotionally, though, I deeply, fundamentally believe in each individual's intrinsic value that lies snugly within the context of their own life, experience, and connections. It's not our biology that makes us valuable, but our humanity. Biologically, maybe we're Earth's (as well as our own) most damaging parasite, devastating the planet, each other, and ourselves. But, then you look at our humanity and we are every bit as beautiful as we are horrendous. We are every bit deserving of the life we allow for ourselves.

another idea: mosquitoes serve as human population control. in general, it seems we can take an objective look at the roles various species take in ecological life cycles, and we maintain through all kinds of ecological campaigns to save endangered species out of a desire to maintain ecological homeostasis and equilibrium; and yet, we DO want to eliminate a species that slows down our own overpopulation. hmmm.... we say mosquitoes have no redeeming features, but maybe our perspective is warped by our own propensity to reproduce and thrive, even as we destroy ourselves and the world as it sustains us.
