Epimetheus

The brother of the wise Prometheus, Epimetheus' name means 'after-thought.'  True to his name, Epimetheus is an impulsive idiot.  Saved by his brother  Prometheus from fighting for the Titans in the Titanomachy, Epimetheus was spared an eternity in Tartarus.

After being warned by Prometheus to accept no gifts from Zeus, it was also Epimetheus who accepted Pandora to be his wife, and thus brought about the ills of the world upon mankind.
