Is Osama bin Laden really more evil than Adolf Eichmann was?

osama bin laden declared war on the united states. He was an ENEMY of the united states(at war with the USA). In a war you do not have to give the enemy a fair trial. If we were to give osama a fair trial, that would mean we would have to give a fair trial to every german and japanese solider america was at war with in ww2
