At school we had a discussion about our motives to do certain things. The concrete example was Antigone. Antigone buries the corpse of her brother, which is against the law, and risks her own life by doing so. Finally she gets caught and is sentenced to death, but before that can happen, she kills herself. At first I thought this was the greatest love one can prove to another. But a classmate said everything we do has an egoistic motive. Antigone didn't bury her brother to give his soul rest, but to give herself a good feeling.
My question is: What we experience as love, is it really caring about someone or just trying to feel better?
