Finally someone else said it. Females are attracted to violence, or more precisely to dominance expressed through the capacity for violence. Across species, including humans, females tend to select mates who show traits linked to survival and reproductive success: strength, aggression, territoriality, and the ability to dominate other males. A male who can fight off rivals, secure resources, and protect offspring is more likely to pass on his genes. Over time, females evolved to prefer those traits because they gave their young a better chance to survive.
Examples are widespread in the animal kingdom. In gorillas, females mate with the silverback who controls the troop. He is often violent, aggressive, and dominant. He fights off challengers and asserts control through force. In lions, the dominant male drives off or kills competitors. When a new male takes over a pride, he may even kill the cubs of the previous male so the females return to estrus. In elephant seals, males battle violently for beach territory. The winner secures a harem and breeds with dozens of females. The losers are forced to retreat. They get no access because the dominant male defends the territory and drives off challengers.
