Stargate SG-1 - Goa’uld - Moloc.
This Goa’uld made the not very future-savvy choice to kill all female Jaffa children, since he only wanted men for his battles.
The Hak’tyl (‘liberation’) and their leader, the Jaffa priestess Ishta, managed to save many of these female children.
Moloc was killed by a hell-fire missile.
We have seen Moloc in the episode: “Sacrifices”, and he is mentioned in the episode “Birthright”. Moloc is played by Royston Innes.
