הַאי מַאן דִּבְמַאְדִּים — יְהֵי גְּבַר אָשֵׁיד דְּמָא. אָמַר רַב אָשֵׁי: אִי אוּמָּנָא, אִי גַּנָּבָא, אִי טַבָּחָא, אִי מָהוֹלָא. אָמַר רַבָּה: אֲנָא בְּמַאְדִּים הֲוַאי. אָמַר אַבָּיֵי: מָר נָמֵי עָנֵישׁ וְקָטֵיל.

One who was born under the influence of Mars will be one who spills blood. Rav Ashi said: He will be either a blood letter, or a thief, or a slaughterer of animals, or a circumciser. Rabba said: I was born under the influence of Mars and I do not perform any of those activities. Abaye said: My Master also punishes and kills as a judge.

Maharsha

יש לפרש דלא נגזר אלא שיהא אשיד דמא ולפי בחירתו של אדם אי אומנא שהוא רשות אי גנבא שהוא איסור ואי מוהלא שהוא מצוה:

In psychology, sublimation is a mature type of defense mechanism, in which socially unacceptable impulses or idealizations are transformed into socially acceptable actions or behavior, possibly resulting in a long-term conversion of the initial impulse.

Sigmund Freud believed that sublimation was a sign of maturity and civilization, allowing people to function normally in culturally acceptable ways. He defined sublimation as the process of deflecting sexual instincts into acts of higher social valuation, being "an especially conspicuous feature of cultural development; it is what makes it possible for higher psychical activities, scientific, artistic or ideological, to play such an 'important' part in civilized life."[1] Wade and Travis present a similar view, stating that sublimation occurs when displacement "serves a higher cultural or socially useful purpose, as in the creation of art or inventions."[2]
