When good should be bad.

Ever consider robbing a bank? Slipping an object from a store into your pocket without paying? Not me.
I've always tried to be a good person my whole life. When I play a video game I end up being the good guy; even if there is a bad guy to choose. On that same note, games that portray only evil are ones I hardly ever play (I never said I am against them). Being bad, virtually or otherwise, isn't something I think about ... much.
I think this flows over into my writing. This is the thought that rolls through my head sometimes. "Why not write from the bad guys prospective?" "How far is too far for the bad guys to attack my hero?" Other questions bounce around as I work out details with my writing. Thinking out of the safe little box I've built around my life and thinking has limited how I write.
Sure, I've watch movies, read books, and seen terrible images on the news. It doesn't mean I store it away for a rainy day. There is a mind dump shortly after viewing or reading such things. No need to keep horrible stories locked up in my mind. Now, I find a need to remember what people have done so I might get a feeling of their mindset when they did those robberies or killings. The honest truth is someone must write unthinkable situations for innocent people to be stuck in and they won't always be nice.
The point I am trying to make is this - even the nicest person thinks bad thoughts. Stuff happens and mostly to the good people in spades. It is my job, and those writing scripts or producing movies, to give a clear picture of certain events without going overboard with scenes entailing blood and guts. Make it entertaining while still allowing the mind's eye to draw the picture as the story unfolds.
