Being created in the image of G-d is a a philosophical statement found in the first chapter of B' rayshit. But being created in the image of G-d can mean different things to different people from different cultures. However, the ninth chapter of B'rayshit brings the philosophy down to reality. An image of G-d has obligations and even in the heat of anger, passion, or jealousy, those responsibilities must be upheld. Similarly, being a Child of G-d is a beautiful concept.
Philosophy can twist the concept to mean just about anything.
But again the Torah defines this philosophy in concrete terms. Again, we find obligation and responsibility taking precedence over philosophy. Rebbi Akiva's message is just that. Man can twist philosophy to contain beautiful and eloquent statements that do not necessarily affect one's behavior. The Torah contains much philosophy but it also merges those philosophies into obligations and responsibilities, superseding our passions and desires and elevating us to a higher plane of life.
