How can nonvegetarians call themselves kind?

They are killing animals/getting them killed for their taste buds. Don't start with vegetarians kill plants too, because they eat the already dead plant and even help in their dissemination. And last time I checked there has been no vegetable crying for help while getting its throat slit. Come on people! Why do you need to take a life for your pleasure? And vitb12 from milk, and yogurt is enough. Liver stores b12 for 3 years and even if all dietary intake is stopped it takes years to develop deficiency.
