How does the prospect of sitting in jail for six months affect you?

First of all--six months. 
While it's not as long as some other sentences, it's still a long time. 
And that's six months of me being surrounded by people that did these actual crimes, 
did bad things to other people, to humanity. And I'm surrounding myself with these people that are lower than myself. 
Not to sound arrogant, but they lack morals, and it would be degrading to my character . . . and I'm worried.
