“Heretics cannot themselves appear good unless they depict the Church as evil, false, and mendacious. They alone wish to be esteemed as the good, but the Church must be made to appear evil in every respect.”
Dictata super Psalterium (Dictations on the Psalter). This is Luther's first major work from the years 1513 to 1515.

Context: There is no principle worth the name if it is not wholly good. I swear by non-violence because I know that it alone conduces to the highest good of mankind, not merely in the next world, but in this also. I object to violence because, when it appears to do good, the good is only temporary, the evil it does is permanent.

“A good End cannot sanctifie evil Means; nor must we ever do Evil, that Good may come of it.”
537-539
Fruits of Solitude (1682), Part I
Context: A good End cannot sanctifie evil Means; nor must we ever do Evil, that Good may come of it. Some Folks think they may Scold, Rail, Hate, Rob and Kill too; so it be but for God's sake. But nothing in us unlike him, can please him.

“Every political good carried to the extreme must be productive of evil.”
The French Revolution, Bk. V, ch. 4 (1794)

“The worst evil which can befall the artist is that his work should appear good in his own eyes.”

XII. The origin of evil things; and that there is no positive evil.

Context: “Sisters,” she began, “let me tell you what is happening, and who it is that we must fight. It is the Magisterium, the Church. For all its history—and that’s not long by our lives, but it’s many, many of theirs—it’s tried to suppress and control every natural impulse. And when it can’t control them, it cuts them out. Some of you have seen what they did at Bolvangar. And that was horrible, but it is not the only such place, not the only such practice. Sisters, you know only the north; I have traveled in the south lands. There are churches there, believe me, that cut their children too, as the people of Bolvangar did—not in the same way, but just as horribly. They cut their sexual organs, yes, both boys and girls; they cut them with knives so that they shan’t feel. That is what the Church does, and every church is the same: control, obliterate, destroy every good feeling. So if a war comes, and the Church is on one side of it, we must be on the other, no matter what strange allies we find ourselves bound to.

“False words are not only evil in themselves, but they infect the soul with evil.”
Phaedo 115e
literally: 'For know well', he said, 'o dearest Kriton, that to not speak well is not only sinful by itself, but lets evil intrude into the soul.'(εὖ γὰρ ἴσθι, ἦ δ᾽ ὅς, ὦ ἄριστε Κρίτων, τὸ μὴ καλῶς λέγειν οὐ μόνον εἰς αὐτὸ τοῦτο πλημμελές, ἀλλὰ καὶ κακόν τι ἐμποιεῖ ταῖς ψυχαῖς.)
