How is the charecter of chris couraryof to that of hisfather in "All of my sons" ?

I assume that you are asking for a comparison of the two. Unlike his father, Chris returns from the war and finds the narrow confines of civilian life stifling. Where Joe Keller is satisfied with the boarders of this small town, Chris has seen too much (in the war) to simply settle down into family friendly bliss. Chris, like his father,is devoted to his family but, unlike his father, is perplexed by the war. He has trouble coming to terms with his father's successful business which profited from the war. His father sees nothing wrong with the relationship between his business and the war. THere are of course secrets to uncover which changes the dynamic between the characters.
