“Can it suffer” is relevant when the decision is about its suffering. “How much is its potential future life valued” (by humans, and by itself if it has a concept of the future) is more relevant to killing in particular. Arguably you could weigh the suffering involved in an immanent death more than the suffering in a much later death.
