President Kennedy's assassination was not the first time Lee Harvey Oswald harmed another person; he has an extensive history of violence. Oswald had committed other assassinations and is rumored to have been physically and verbally abusive to his wife, Marina. His known anger issues combined with his strong distaste for the United States government and past military experience pushed him to assassinate President Kennedy out of pure hatred. Oswald was constantly arguing with Marina throughout their marriage. Often their fights would end in Oswald physically abusing her. Marina and their children would regularly move in and out depending on how severe and frequent the abuse was. Approximately six months before JFK's assassination, Oswald attempted to assassinate General Edwin Walker because he was a right-wing extremist. Despite being a short distance from his home office window, Oswald missed and Walker only got shrapnel into his arm.
The claims that Lee Harvey Oswald was abusive to Marina were never proven true. Additionally, no one reported spotting Oswald trying to shoot General Walker. Oswald could have been lying about the assassination attempt for personal gain. Therefore, it is unfair to assume that either of these accusations against Oswald is true since they are not proven.
