no good deed goes unpunished

• no good deed ever goes unpunished

According to the website Grammarist, there is no one origin for the phrase "let no good deed go unpunished." However, it also lists several written examples from the 20th century, starting with a 1942 phrase attributed to Walter Winchell, in which he wrote (in a column) "[It] reminds me of the line diplomats use: ‘No good deed goes unpunished in Washington.” On top of that, it lists one from Dante's "The Divine Comedy" ("love is the seed in you of every virtue/and of all acts deserving punishment.").

Meanwhile, the website Quote Investigator gives several older examples of these phrases, including one from a 12th-century text that was translated into English in 1923, and which discussed a malevolent, though the website indicated that it wasn't written like it was a proverb. As well, two came from 1927 (one of which used the word "kindness" in place of "good deed") and another from 1938 ("Every good deed brings its own punishment"), which was the earliest match that website found which it considered to be strong.
