Females = righteous ; males = evil pieces of sh*t

Simple:
It's a Romeo and Juliette love story, where males are sinners and attracted to powers only. In the meantime, females are good persons, witches won't kill witch hunters when those are females (but killing males is alright).
The storyline is entertaining without being amazing nor surprising (Romeo/Juliette in a witch hunt context). But the moral is rotten and misandre to its roots
