Loosing consciousness of oneself is what makes good people do bad things.
Explanation:
There is in deed a wide number of circumstances that makes good people do bad things; personal background, mental health, hidden desires or even the sense of self satisfaction.
However, it all goes down to a single moment: Choice. It is what really matters, we choose whether to do something bad or not and all this depends on how conscious we are of our own actions. The moment we lose our primary consciousness, we then lose all the inhibitors that have been constructed all around us by different sources such as society, religion or personal beliefs and family. Losing the notion of who we are and what is wrong or right simply lead us to a mental state of behaving just by instinct which ultimate leads to do bad things not even realizing how bad they really are.
