As far as turning actual human or animal waste into compost, I'd say Google is your best bet for info on the subject.

Negative Nellies on the other hand, I suppose one good way to make something positive out of them is through observing how they perceive things and try to keep yourself from being influenced to see things that way yourself.

Yes, I've composted my dog's waste, but it's generally only good for the lawn. Don't try and use it on food, but human waste might be okay. I'd look it up first.

Yes, but it takes a lot more time (and work) to compost fecal matter (or meat) than ti does vegetable matter. The issue is in how long it takes to for bacteria in fecal matter to become neutralized. A lot of food recalls are due to food having been grown in 3rd world countries but sold here, where in the 3rd world they did not allow adequate time for all bacteria to neutralize before using compost to grow food that ends up beign sold here in the U.,S.

There are website to tell you how to do it, but rather than Googling "compost shit" you might try substituting "fecal matter" or "animal wastes" in your searches.
