I think a person would be considered "bad" if they keep repeating the same action. For example, I wouldn't call a person that did cocaine once or twice a drug addict, but if they used it every day I would. Although I will admit that some actions, to me, are unforgivable even if they were only committed one time. Pedophilia comes to mind.
"My life has taught me that true spiritual insight can come about only through direct experience, the way a severe burn can be attained only by putting your hand in the fire. Faith is nothing more than a watered-down attempt to accept someone else's insight as your own." -Damien Echols
