Quote #4
All the same, there had been deadly days when she could not keep from picturing the enormous happiness she'd taste if, having become a widow, she was able to marry Julien. (1.23.66)
Madame de Rênal is a moral woman. She knows she'll never be able to live openly as Julien Sorel's lover. But she does fantasize about her husband dying so that she can respectably be with Julien. She doesn't seem to realize that it's not all that nice to fantasize about people dying.
Quote #5
What strange effects marriage has, in the form practiced by the nineteenth century! The boredom of married life certainly kills love, if love has preceded marriage. (1.23.68)
Stendhal isn't giving us a ringing endorsement of marriage here. He directly tells us that getting married tends to kill whatever love two people used to feel for each other.
Quote #6
"And I'm going to seduce his daughter—me! Perhaps her marriage to de Croisenois will be impossible—a marriage that glows in Monsieur de La Mole's future." (2.13.24)
Julien Sorel feels his ego glowing when he thinks about seducing Mathilde de La Mole. He gets a real kick out of the thought that sleeping with her will ruin her chances to marry a respectable man like her father has planned. Julien usually feels grateful toward the Marquis de La Mole, but here we can see his hatred of the upper classes shining through.
