Subject: Can persons with a strong sense of justice be genetically engineered forth?

It has been much mentioned by various instances that when the science of 
genetic engineering reaches a certain point, intelligence and various other 
aspects I would caracterize as a part of a persons "personality" will be 
tinkerable. Since intelligence seems to me to be quite an abstract concept, I 
wonder if a strong sense of justice or perhaps a disinclination to materialism 
would be possible to create in a human through engineering? Is there any good 
literature you can refer me to about what is believed to be a result of 
genetics or society when it comes to personality traits?
