what happens when victor confesses to the crimes?

Victor tells his father that he is the true engineer of all the catastrophes that have befallen them, but Alphonse attributes his confession to delirium. When his father begs him not to say such dreadful things, Victor replies that he would gladly have died in their place, but that he could not sacrifice all humankind to save those whom he loved. At length, Frankenstein is able (albeit through "the utmost self-violence") to control his desire to declare his guilt to the world.
