Traits of alpha males, the leaders and dominators of our species, range in good and bad. Aggressiveness and patriotism are the main qualities of alpha males. Skillfulness, authority, and sexual access to women are also properties that male leaders posses. Females find dominance and power preferable in a man. While men have evolved to be demonic, it seems that women have evolved to prefer demonic males as mates.
Gangs are the most obvious signs of alpha males.
Strong, power-seeking males band together in groups and demand power and respect. Males in gangs are feared and respected. They have been known to show ruthless signs of aggression and violence, including rape and murder. It is not uncommon for a gang to draw innocent blood just to prove their dominance. Gangs are known to hunt down rivals and hurt or kill unknown males who wander into their territory.
