The SR model helps us to make better predictions - but it is not absolute. In the end, qualia (pain/pleasure, likes/dislikes) is a very personal matter and is not constant - today your dog might do his trick for a reward of Bacon Strips, but his tastes may change at any time [even during a dog show] and it might now require a Pupparoni to get him to run the course. Lion tamers have weapons for a reason.
Love is qualia also since it can only be experienced and cannot be fully described. Love means different things to different people and at different times. The expression of a man laying down his life for his friends speaks to the greatest love.
BTW, I saw a film once of a most amazing case of altruistic behavior in the wild. A mother moose was standing with her calf when an Alaskan Brown appeared in the distance. She nudged the calf down to the ground and ran straight to the bear. She made a choice to be eaten contrary to her self-interest - and acted on it. I havent seen this kind of behavior outside of herds. And in the herds, such as the Black African Buffalo, it is the male who goes back to confront the predator in a battle to the death (which he often wins) - not to offer himself as an alternative dinner.
And getting back to humans (v animals) I find it particularly interesting that most all animals are born with both the ability and the instinct to find their mother's milk - but a human baby must be literally brought to the stimulus. It is as if human mothers are forced to the decision and action with a deck stacked against the newborn as the mothers pain is so intense during childbirth shes apt to want to die or kill the man who did it to her. The only advantage the newborn has is that the human mother forgets that pain almost instantly.
Even so, some humans and animals are known to abandon their young. They love less it would appear.
Great stories about the mother moose and the black buffalo. There is definitely an awareness that is part of what drives them to do what they do.
Then there are the stories of incredible loyalty shown by some pets to their humans.
And some humans to the families, neighborhoods, nations.
Determinism is not the final word.
