Interesting point about subjectivity. I do agree, I just wonder if focusing purely on the actual death (severing of the neck vs. throwing in a river) matters that much?
What about the pain/incarceration suffered during an animal's life? What about the fact that the animals life is being cut short (regardless of method)? Surely these things have to be taken into consideration too?
For example, what about chicken farming vs fox hunting?
during life, the (battery) chickens are kept in uncomfortable conditions vs. the fox, which runs free
both animals lives are cut short (not sure of the comparative length of life)
chicken is killed "humanely", fox is scared and hunted
To me, it is very hard to say which of these is crueller than the other - but most people seem to (indirectly) condone the chicken farming but condemn the fox hunting, because they only consider the actual killing of the animal.
