Not every person who wore the Captain America outfit was sane. William Burnside was infatuated with Steve Rogers. Burnside found the super soldier serum while in Germany. The US Government found out and gave him a costume to wear, so Burnside could fight the good fight during the Korean war. Burnside had the powers of Rogers, so his next step was to get plastic surgery to look like him and to legally change his name to Steve Rogers. After the war, Burnside lost his mind and tried to kill people and himself. He also attempted to kill Bucky Barnes and tried to get Bucky to wear his costume from World War II.
