suggesting that animals eating other animals is bad does not imply that killing all carnivores is the correct solution to that problem. there is no solution to that problem which would save the lives of every animal alive today, so any solution to this problem must include the death of some animals. "continue letting animals eat other animals until we can find a real solution that won't destroy the biosphere or genocide billions of living creatures" is a valid solution even under the strict idea that killing animals to eat them is always wrong
