The missing word is Compensation.
Alfred Adler was known to be a medical doctor, a psychotherapist and is also a founder of the of the school of individual psychology.
According to Adler, individual psychology has got to do with this case wherein Ethan develops strength in other areas such as the compensation. In Adler's theory and principle, psychology owns compensation and overcompensation.
What was the overall purpose for the emancipation proclamation?
Answer: The Emancipation Proclamation was an executive order issued by Abraham Lincoln on January 1, 1863. It proclaimed the freedom of slaves in the ten Confederate states still in rebellion. It also decreed that freed slaves could be enlisted in the Union Army, thereby increasing the Union's available manpower.
So I think it would be: to end slavery everywhere in union
