Okay, you account for Albert's possible reasoning a half-century ago. As we all know, a privileged man can deny and double-down until the clock runs out, but it never diminishes the wrong he's done and usually increases the risk of a disproportionate future blow-back. Albert would not have been the first privileged man to behave honorably and discreetly in such circumstances. And once he retired, your above rationale ceased to be a critical factor. But he (and Paola?) continued the course of total denial, and in response his daughter matched that stubbornness and she won.
As for your fears of imagined future scandals due to Delphine's legal award, using purely hypothetical worst-case scenarios to justify one's displeasure seems a bit desperate. No one can say how her future and her children's futures will go.
