Answer: Love for mankind
Explanation:
Prometheus was famous for his philanthropy because he loved mankind and he wanted people to have everything. His love was so big that he stole wisdom from Athene and he also has stole fire from Hephaestus. He was the one who was protecting mankind and he wanted to learn the things that would be useful for them.
Epimetheus was made a mistake because he gave everything to animals and nothing has left for people., then the Prometheus got things right by helping them.
