Sorry this is late :(
So smerdyakov killed fyodor, but only because the gang lord Alyosha told him so. Lise is almost as stupid as that lady from the great gatsby movie...what was her name, Myrtle? the lady that smashed her hand into the glass then started licking the blood off of it. yeah, lise is almost as stupid as her. Alyosha and Ivan are still robots, but Ivan's processor broke down because he saw a devil. Alyosha used his robot skills to calm him down. Smerdyakov the Guitar Hero hangs himself because he knew he would get caught, he only killed Fyodor for inheritance and Gregory is still the best in the whole book.
