A frightful selfishness hurried me on, while my heart was poisoned with remorse.

"Your repentance," I said, "is now superfluous. If you had listened to the voice of conscience and heeded the stings of remorse before you had urged your diabolical vengeance to this extremity, Frankenstein would yet have lived."

My heart was fashioned to be susceptible of love and sympathy, and when wrenched by misery to vice and hatred, it did not endure the violence of the change without torture such as you cannot even imagine.

Urged thus far, I had no choice but to adapt my nature to an element which I had willingly chosen. The completion of my demoniacal design became an insatiable passion.
