“…and from that moment Buck hated him with a bitter and deathless hatred.”
“A bitter hatred was lifting his lip from his teeth.”
“Let us not seek to satisfy our thirst for freedom by drinking from the cup of bitterness and hatred.”
“To wrong those we hate is to add fuel to our hatred. Conversely, to treat an enemy with magnanimity is to blunt our hatred for him”
“The hatred of hatred is still hate.”
“...hate suits him better than forgiveness. Immersed in hate, he doesn't have to do anything; he can be paralyzed, and the rigidty of hatred makes a kind of shelter for him.”
