Does that include the Normans, for whom the Crusade was a land grab from the Byzantines, and violated their oath to return the lands they took? Does it include the Fourth Crusaders, who basically said “Screw it, let’s attack Constantinople instead!”?
Of the major first crusade leaders, there really just two who took it seriously as a religious pilgrimage-Raymond of Toulouse and Bishop Adhemar du Puy.
Stephen of Blois went home, Godfrey and Bohemund broke their oaths to Emperor Alexius, Tancred went off to Edessa…the leaders of that crusade really were not holy men.
The second crusade didn’t have all that much to do with Jerusalem, either. The city was already in Christian hands, and while King Louis VII wanted to go to on a pilgrimage, Conrad got some bizarre idea to and take Damascus to rescue Baldwin from captivity (Baldwin had the same foolhardy idea and got himself captured), and got the army destroyed.
The third crusade was aimed at Jerusalem, but Richard and Phillip were too busy feuding with each other to get their act together. The fourth crusade was a mess, and is really a war between Venice and the Byzantines.
By the time you get to the Fifth Crusade, nobody was even trying to go to the Levant.
