When a person becomes a hater he actually becomes a coward

“A man that flies from his fear may find that he has only taken a short cut to meet it.”
― J.R.R. Tolkien, The Children of Húrin

“Our doubts are traitors,
and make us lose the good we oft might win,
by fearing to attempt.”
― William Shakespeare, Measure for Measure

“In a word, I was too cowardly to do what I knew to be right, as I had been too cowardly to avoid doing what I knew to be wrong.”
― Charles Dickens, Great Expectation

“To say you have no choice is to relieve yourself of responsibility.”
― Patrick Ness, Monsters of Men

“A coward is incapable of exhibiting love; it is the prerogative of the brave.”
― Mahatma Gandhi

“Hatred is the coward’s revenge for being intimidated.”
― George Bernard Shaw

“Tolerance of intolerance is cowardice.”
― Ayaan Hirsi Ali

“The real hero is always a hero by mistake; he dreams of being an honest coward like everybody else.”
― Umberto Eco, Travels in Hyperreality

“But the only way never to do the wrong thing is never to do anything.”
― Jim Butcher, White Night

“Son, never trust a man who doesn’t drink because he’s probably a self-righteous sort, a man who thinks he knows right from wrong all the time. Some of them are good men, but in the name of goodness, they cause most of the suffering in the world. They’re the judges, the meddlers. And, son, never trust a man who drinks but refuses to get drunk. They’re usually afraid of something deep down inside, either that they’re a coward or a fool or mean and violent. You can’t trust a man who’s afraid of himself. But sometimes, son, you can trust a man who occasionally kneels before a toilet. The chances are that he is learning something about humility and his natural human foolishness, about how to survive himself. It’s damned hard for a man to take himself too seriously when he’s heaving his guts into a dirty toilet bowl.”
― James Crumley

“I’m astounded whenever I finish something. Astounded and distressed. My perfectionist instinct should inhibit me from finishing: it should inhibit me from even beginning. But I get distracted and start doing something. What I achieve is not the product of an act of my will but of my will’s surrender. I begin because I don’t have the strength to think; I finish because I don’t have the courage to quit. This book is my cowardice.”
― Fernando Pessoa
“So you were going to rescue the Prince! Why did you pretend to run away? To deceive the Witch?”

“Not likely! I’m a coward. Only way I can do something this frightening is to tell myself I’m not doing it!”
― Diana Wynne Jones, Howl’s Moving Castle

“Long before morning I knew that what I was seeking to discover was a thing I’d always known. That all courage was a form of constancy. That it is always himself that the coward abandoned first. After this all other betrayals come easily.”
― Cormac McCarthy, All the Pretty Horses
