Why do people indulge in bad things?

The allure of being bad or doing the bad thing has been around for a lot of years. Many do it becuase it is a challenging mystery, a part of the growing-up stage and other sod it for the thrill. I guess that there is pleasure in doing bad things and people get addicted to that pleasure and comfort that they don't want to let go or care if other people are being concerned for them. I think what people attracts them to the bad is the its perception of the forbidden. When we are young, we were told about the right and the wrong things. We are expected to do the right things. As we grow older, we try to be (or perhaps, meant to be) adventurous even though we know that we are going to be hurt one way or another. some people do it in the extreme while other s do it for experimental purposes. I cannot sya that it simply a stage but perhaps a state of mind. If people feel good about doing bad things, chances are, they aren't going to drop whatever they are doing in a drop of a hat.

I haven't really tried any of those bad things you've mentioned, fortunately. Maybe it's a trend these days, some people think it looks cool to get wasted and smoke... and crimes aren't really unheard of anymore, they happen every day so people don't think it's a big deal anymore..

There really isn't a specific answer to that question. Things like cognitive psychology and culture have to be taken into consideration. Not everyone find drinking to be bad, same with smoking. However in Western culture, we are taught not to steal or kill. In a village on the other side of the globe, that may be the only means of survival. In my humble opinion, I find that some people do it for attention, the ability to cope, or through learned behaviors.
