If you live in a house on a block that cleared of native bush to make it suitable for human habitation, then you are benefiting from the killing of animals for human existence. If you use shops and all the other infrastructure of urban and suburban areas, you are doing likewise. If you drive a car on any highway it is likely you will contribute to the estimate 5 million annual reptile road toll that our highway and byways chalk up each year. There are other inconsistencies of values that could be made.
There is nothing wrong with disliking the beheading of a snake for culinary purposes. However, to genuinely equate its right to live with that of a human is ascribe an equal value to the existence of animals and the existence of humans. If you do this, then no farm produce or orchard or plantation products should be consumed as animals were killed to establish such agricultural pursuits and animals such as kangaroos, foxes, rabbits, seed eating parrots, a myriad of insects and other animals are killed in order to maintain the productivity of the vegetation under cultivation.
To equate the right to life of of the snake with that of the cook is actually hypocritical whether one is vegetarian or not. To find it extremely distastful on the basis of personal likes and dislikes is 100% acceptable.
It is worth noting here that the biting reflex may remain intact for several hours following decapitation. So anyone confronted with a situation where a venomous snake has been beheaded, needs to be aware of that and take it into consideration in dealing with the situation, both for their own safety and that of any onlookers. The bottom line... A motionless head needs to be treated as if if it could still bite.
