Passion doesn't count the cost. Pascal said that the heart has its reasons that reason takes no account of. If he meant what I think, he meant that when passion seizes the heart it invents reasons that seem not only plausible but conclusive to prove that the world is well lost for love. It convinces you that honour is well sacrificed and that shame is a cheap price to pay. Passion is destructive. It destroyed Antony and Cleopatra, Tristan and Isolde, Parnell and Kitty O'Shea. And if it doesn't destroy it dies.
