Also appears in why these stories often cycle the female characters out once they get "clingy" (like the ol' woman murdered on her wedding day for manpain shtick) - the story focuses solely on the way the plot effects the male lead, not those around him, especially not women who exist in the plot to dole out emotional support to him whenever it's needed (even when they're tortured, have their friends and family killed etc).
It's all basically tied up in making the lead, historically male, free to go on adventures and seduce many beautiful ladies without any repercussions. Which, to borrow a turn of phrase from D&D, often makes them murder-hobos when viewed from the outside - guys who wander from place to place, no place to call home, no friends, no family, kill people who get in their way.
