“Tito was experiencing that inexorable law of human souls, that we prepare ourselves for sudden deeds by the reiterated choice of good or evil that gradually determines character.”

Context: The choice before human beings, is not, as a rule, between good and evil but between two evils. You can let the Nazis rule the world: that is evil; or you can overthrow them by war, which is also evil. There is no other choice before you, and whichever you choose you will not come out with clean hands.

Non-Violent Resistance - Often misquoted as "You assist an evil system most effectively by obeying its orders and decrees. An evil system never deserves such allegiance."
Posthumous publications (1950s and later)
Context: You assist an unjust administration most effectively by obeying its orders and decrees. An evil administration never deserves such allegiance. Allegiance to it means partaking of the evil.
A good person will resist an evil system with his whole soul. Disobedience of the laws of an evil state is therefore a duty.

Principles of Legislation (1830), Ch. X : Analysis of Political Good and Evil; How they are spread in society
Context: It is with government, as with medicine. They have both but a choice of evils. Every law is an evil, for every law is an infraction of liberty: And I repeat that government has but a choice of evils: In making this choice, what ought to be the object of the legislator? He ought to assure himself of two things; 1st, that in every case, the incidents which he tries to prevent are really evils; and 2ndly, that if evils, they are greater than those which he employs to prevent them.
There are then two things to be regarded; the evil of the offence and the evil of the law; the evil of the malady and the evil of the remedy.
An evil comes rarely alone. A lot of evil cannot well fall upon an individual without spreading itself about him, as about a common centre. In the course of its progress we see it take different shapes: we see evil of one kind issue from evil of another kind; evil proceed from good and good from evil. All these changes, it is important to know and to distinguish; in this, in fact, consists the essence of legislation.

Variant translation: The most momentous thing in human life is the art of winning the soul to good or evil.

Words and Their Meanings (1940)
Context: A great deal of attention has been paid … to the technical languages in which men of science do their specialized thinking … But the colloquial usages of everyday speech, the literary and philosophical dialects in which men do their thinking about the problems of morals, politics, religion and psychology — these have been strangely neglected. We talk about "mere matters of words" in a tone which implies that we regard words as things beneath the notice of a serious-minded person.
This is a most unfortunate attitude. For the fact is that words play an enormous part in our lives and are therefore deserving of the closest study. The old idea that words possess magical powers is false; but its falsity is the distortion of a very important truth. Words do have a magical effect — but not in the way that magicians supposed, and not on the objects they were trying to influence. Words are magical in the way they affect the minds of those who use them. "A mere matter of words," we say contemptuously, forgetting that words have power to mould men's thinking, to canalize their feeling, to direct their willing and acting. Conduct and character are largely determined by the nature of the words we currently use to discuss ourselves and the world around us.
