This is an incredible book. Read it in this translation:

The Brothers Karamazov
Fyodor Dostoevsky (Author), Richard Pevear (Translator), Larissa Volokhonsky (Translator)

It makes a HUGE difference! Garnett translated some things in a such way that it changed the meaning of Dostoevsky. Just compare The Grand Inquisitor chapter in both translations. You will be surprised. Trust me, Russian is my native language!
