The only reason you think that is because their stories were never told to the public. But go a head, live in ignorance, no need to leave kindergarten for our sake.
I'm sorry, do you think that the Disney version of Hercules was accurate? Let me give you a Mythology lesson.
Hercules has among other things...
1) Killed his music teacher Lindos after Lindos struck him for being a poor pupil
2) Cut off the noses and ears of Erginos' heralds
3) Fed Diomedes to his man-eating horses
4) Killed an Amazon queen and with Theseus abducted an Amazon for later ransom (see later)
5) Killed the Moliones at the Isthmian Games as revenge for having defeated his army when he was ill
6) Raped the priestess Auge during a festival of Athena after drinking too much wine
7) Killed Iphitos for not handing over his daughter Iole as promised (despite being married to Deianeira at the time)
8) Enslaves the inhabitants of Omphale
9) Slew Syleus' daughter Xenodike and burned his vineyard
There are other things, I sincerely doubt that all 50 daughters of Thespios consented that night.
Myth Hercules did not subjugate the Amazons (he only seduced their queen and then killed like 13 of them, including the queen, but I guess we'll ignore that too). He did however do all those things mentioned above. So, to say that the comics turned Hercules into something he is not is a flat out lie. Hercules killed innocent people, he conquered cities, he's enslaved people, and he is a rapist. The comic didn't really do anything but, portray the REAL Hercules.
Edit: And Perez did give Herc a redemption ark in Challenge of the Gods. A bit undeserving frankly and it was rather quick.
