Yehuda said to Yossef: והיה כראותו כי אין הנער ומת
I heard an interesting vort. (I'm not very good at repeating such things, so forgive me if it's not well explained.) I can't remember who says it, but when I do I'll post it bl"n.
Yehuda was describing how painful it would be for Yaakov not to see/be with his son. And therefore Yossef should have mercy and let him return home.
Why didn't Yehuda (also) say that it would be painful for Binyomin to be without his father?
The answer is, that the love of parents for a child, is much stronger than that of a child towards his parents. the reason for this is genetic. Odom HoRishon didn't have any parents, so he had no in-built love towards parents. But he did have children, and thus a love towards his own children. Therefore a parents love for a child is much greater.
