Including all living creatures isn't quite useful in terms of survival chances. Thinking about this topic, we could also philosophize the whole "torture" aspect. Presumably it means physical pain to an animal which many feel uneasy about. But if you think about it, pain, as signals to the brain are also evolved mechanisms in order to survive. Pain is a crude signal indicating that the life of that animal is in danger but they are not perfect indicators. If pain signals were more accurate they would activate the moment an animal approaches a human with a shotgun similar to how you feel pain touching boiling water. But the pain mechanism hasn't become that sophisticated yet. So even the pain is an arbitrary crude mechanism so real "torture" would be loss of habitat for example but animals won't feel that as pain.
