how else am i to absorb their soul

Tell me more about how you have to resort to using artificial sources of B12 because your diet doesn't naturally contain them.

I'd rather have to take an artificial, plant-based source of B12 than kill and torture an animal who doesn't want to die.

It does not exist. That is why vegans have to eat fortified (that means artificial) foods. Veganism is just not natural. I think It's "weird and crazy" to eat foods created in a lab just to avoid the natural order.

Eating meat and animal products has nothing whatsoever to do with the natural order. Humans can't kill animals with their bare hands and they buy the animals in supermarkets. This has nothing to do with the natural order that exists in nature. If it was natural, we would be able to kill the animals with our bare hands, like lions and tigers can do. Our canines are puny in comparison to their's and our digestive system is designed for plants, not for animal products. The only reason why there is B12 in dead animals flesh and in their secretions is because the tortured animals are fed plants, which is their only source of B12, protein, calcium etc. B12 can therefore be found in plants and is easier for our bodies to absorb. Again, I'd rather take a supplement than contribute to torturing animals. Fortified foods are not necessarily artifical. Soy yoghurt, for example (rich in B12 and calcium), is high in these nutrients because of the fermentation process.

Humans naturally scavenge eggs and other predators abandoned kills. Most often marrow by breaking open the bones.
As to b12 being available in plants, Learn to use Google. The ONLY reliable vegan source of B12 is fortified (artificially added) foods. Yes, soy yogurt contains b12, because it has been artificially created to mimic regular yogurt.
