in a lot of cases, som1s upbringing can have alot to do with their behavior but that can be an excuse as well... i was raised in one of the worst parts of arkansas (Pine Bluff and Little Rock), poor, gangs everywhere, drugs, drive bys, all kinda shit.. but MY PARENTS and their example that they set for me had the most to do with the ME now. Never had a smoke of Any kind, and neither have ever had a sip of any kind alcohol.
IMO, what really matters is what goes on in the home..
