Is it possible for someone to be good and bad at the same time?

I mean, how do you define good? 

For that matter, how do you define bad? 

Is being bad the same as being evil? Or is it simply that you enjoy doing things society doesn't approve of, but aren't necessarily evil?

In that case, aren't you simply being good inherently, but bad exherently? 

Where do you draw a proper line, if at all there is a line?

The line itself is subjective, isn't it? In the same city, some people will call me an evil to society if I drink and get smashed and wobble home. Others will call me a 'real party animal'. So long as no one's getting hurt, does that make it bad?

On the other hand, I could be doing this, not hurting anyone, and have a devout faith and am good to everyone, totally forgiving etc.

Now what?
