By way of expanding upon my comment above...let's try to remove ethics and morality from the discussion. All animals that live in groups have 'rules' that protect the group from behaviors that threaten the group's existence. A group member who behaves in an way that threatens the group itself, is shunned, ostracized, or killed. Human society is no different. During relatively modern times, we have adopted written rules of behavior with procedures to judge and punish violators to the extreme of imprisonment and even death. And prison populations throughout the world are overwhelmingly male. Further evidence that there is almost certainly a biological/genetic factor causing males to behave in a manner resulting in society imprisoning males at a much higher rates than females. To be clear, it is also very true that only a small percentage of males are ever charged with criminal (anti-social) behavior. So, there are obviously other factors involved beyond just being male. However, that doesn't change my point that genetic traits almost certainly play a role. There is a huge body of science that has been studying human anti-social behavior for centuries.
