If you compare the "Good Soldier Defense" with the "Battered Wife Defense," you could claim that both are defenses for perpetrators of crimes who may or may not have gone through traumatic experiences that have shaped the behavior that led to the committing of what is regarded as crime.
And yet the US Senate decides to effectively scrap the "Good Soldier Defense" in most cases, but the "Battered Wife Defense" is beyond reproach? Doesn't that seem just a little bit hypocritical?
