Pride or shame is by definition a feeling not legal culpability. A feeling.
Human brains seem wired to have strong feelings about their kin or tribe. So, yes, I would think having neutral feelings about your parents would be a hard thing to understand for most people.
From a purely logical point of view - there's not much point to anything humans do.
Can you break down what the logic of pride should be? Any who determines what that should is. You seem to imply that there's an objective standard for that.
Will you send a child to prison for crimes committed by their parents if the parents ended up dead by the time found guilty?
