Logan is a man very intelligent and serious and smart. Even more in the years 1943, since not everyone can do big studies a lot of peoples believe his lies and see him as a genius, who can heal brains. But all of it is fake. He have a big team who work with him on all subject. It is only free remunerated experiences to Logan. “If they really love and care about their partner/children why would he want to take off a part of them ?”. With this way of see it, he have no regret or sympathy for them.
