I downloaded this image a number of years ago, can't remember where and can't provide attribution: apologies to the copyright-owner. Actually it's unclear as to whether dolphins were granted legal personhood status, or whether India "merely" banned the use of dolphins in aquatic theme parks. But whatever happened in reality has no bearing on whether cetaceans are or are not persons, or on how they should be treated. This issue is a great example of the relativity of values and the significance of context. The movie,
Free Willy, is about the conflict of values and the impact of that conflict on the life of an orca named Willy. Many humans, including myself, believe that cetaceans are as "personable" as humans.
Free will means you are free to choose to do anything that is within your power to do; to think anything that is in your power to think; to experience anything that is within your power to experience. But the most significant freedom of all is the freedom to define your values, relative to the All, relative to Everything and every thing.
That relativity is inescapable, at least for the likes of you and me. You might, for instance, choose diversity as one of your values, except if you were supplying tomatoes to a supermarket, in which case you would want all your tomatoes to be the same size, weight and color. A supplier of tomatoes to a supermarket would prefer conformity to diversity, at least in relation to supplying tomatoes. To echo the "location, location, location" of realtors: context, context, context!
