I don't want to be rude or anything but I think you should consider the fact that a)the octopus would probably suffer just as much had it been eaten by a natural predator in its natural environment and b)livestock such as cows or pigs surely suffer a lot more during their lives because of poor living condisions than this octopus in its last 30 seconds, and that suffering is surely more common.
Natural selection is totally fine by me. But when speaking of humans having a good time chewing up live animals, it bothers me. I guess i'm a sensitive person.
What the fuck does any of what he said have to do with natural selection? Your argument is weak, bordering on incomprehensible and you're embarrassing yourself.
