> I might be biased but those that chose to quit military service more often than not drifted into the sidelines in terms of career, social integration, and other aspects.

When you phrase it like this, it seems to me that you value having a good career and social integration.

On the other hand just seems to me that one's career and social integration is exactly the sort of thing that someone who quits conscription values highly. Without more information, it seems to me that such a person as you describe may consider themself to be leading a good life (in terms of satisfaction and/or morally).
