Is There a Meaningful Use of the Word Moral Worth?

A, i am committed to the view that pleasure and pain, if that is what grounds moral worth. And s a question for me as to whether there's kind of a meaningful use of the word moral worth,. That is in any sense objective. A, but i think if we take the view that suffering is what matters, then i think i would just be committed to the idea that if other animals can suffer more, they are worth more for that reason. So maybe suffering isn't all the matter. You know, i don't really know. It's hard, isn't it?
