It's so true! XD Hera is the wife of Zeus father of Hercules. Zeus had an affair with Alcmene. Hera, who is kept from punishing Alcmene by Zeus and can't punish Zeus for his infidelity, instead punishes Hercules. When Hercules is a baby she sent two snakes to his crib trying to kill him - only he strangled them instead. Then years later she drove him mad resulting in him killing his wife and three children. As a result to pay for his crimes he would do the 12 labors to earn the forgiveness of the Gods. So yeah. Worst step-mother ever. Definitely beat out any of the Disney evil step-mothers. lol
