Heracles abandoned his duties to go kill the Hydra, which was just minding it's own business in a swamp. The rest of his famed "12 labors" were punishment for murdering his family, and for causing wanton destruction while preforming the labors. His 2nd or 3rd wife killed him using hind blood because he was cheating on her.
ummmm, i remind you than Herakles (not hercules, and even then) in the original myth the only true evil action he made was with the murder of Charion which he got traumatized, the rest of his evil actions were thanks to Hera who hated his gutts and wanted him in Tartarus; he was mastered (using Worm Terms) to kill his wife and son (both who he loved) and then was exiled in order to make sure than he do not go against "
hera's chosen" his brother (which was the king only because Hera wanted), after that Zeus helped him a lot and Hera in fits of rage tried to kill him a lot of times (or send him to die) making the 2 labors.
the Nemean Hydra was him just killing a monster of the gods.
what you are refering, and being honest in a bad way, is the movie
Herakles; which it has little to do with Mythology an like "Hercules" from Disney "make him a christian hero" they make him with it a "Greek Monster".
a lot of stories of the heroes commiting evil actions were ultimetly fault of the gods themselves, Medea killing her family and trying to kill Jason?
she was Forced by Aphrodite to "truly fall in love" with jason (which i sure it would perfectly fit in the troupe "Jackass") and Jason ordered her to do those acts, and with the order in place she was litterally frced to do it without another choice, not mattering if her father loved her (he was) or if she loved her brother (she loved him) or if the country loved them (they done it) and at the end she tried to kill Jason not only because he dihed her but because she got free of the "lvoe" and wanted to make him pay for what he has done to her.
in WORM terms: Heartbreker (correct me if i am wrong) kipnap a preatty woman, he absolutly make her depending on him, order her to kill her father and brother who she loves, she makes a lot of evil things becase he ordered her and at the end she get's diched because she is not funny anymore she triggers becoming inmune to her power in the way and tries to get revenge against him at any way.
pretty mch any greek story can be resumed "the gods (except Hades) making Humans misarable because YES)"
Thus why I like to point out there are many versions of most myths.
and the mayority still has the elements of before.
so the point is not valid.
