Will abolishing guns in America reduce violent crimes?

I don't think abolishing guns in America is possible now because American society is completely floded with guns and in addition to that huge number of "illegal" guns are already in the hands of  "bad guys" which is nearly impossible for the government to control. On the other hand; NRA is strongly advocating for the right to have guns for self-defence.

Besides this; I have an impression that many people in America enjoy hunting or killing innocent animals/birds for "FUN" which reflects their insensitiveness to killing. I have even seen some parents braging about their small children for being able to use a gun.   How can such society be violence free?
