Is there a specific word to describe the opposite of egotistical - acting for the specific benefit of someone else?
Perhaps this will fill the need;
al·tru·is·tic
/ˌaltro͞oˈistik/
adjective: altruistic
showing a disinterested and selfless concern for the well-being of others; unselfish. "it was an entirely altruistic act"
synonyms: unselfish, selfless, compassionate, kind, public-spirited; More charitable, benevolent, beneficent, philanthropic, humanitarian;
"the desire is to appear purely altruistic with no apparent expectation
Perhaps
empathetic (adj):
