The concept of perfection/imperfection is based deeply in Judeo-Christian doctrine. All humans deal with greed, anger, and ignorance. It is part of the human experience. In that sense, we are all perfectly human.
When, where, and how we are raised all lead to concept or ideas that shape or view of reality. Some are right and others not so much. We act on our views.
No matter the case, we are all 100% responsible for our action. All of our actions effect someone else. One of the biggest lies we tell ourselves is that an action will not harm anyone else. Lies such as "What they don't know can't hurt me or them" spurs on wrongdoing.
So being raised as one of Jehovah's Witnesses can cause a person to have the wrong view or idea of something. In addition, people tend to turn to narcotics, alcohol, sex, food, and a whole list of things to deal with the mental anguish caused by wrong views. However, this is never an excuse to the choices we make. "We're all imperfect" is not an excuse to wrong doing.
I also do not subscribe to the Judeo-Christian doctrine of crime and punishment. I believe much of this is an egocentric exercise where labels diminish the wrongdoer to make others feel self important. The idea that a person must feel pain and suffering for breaking a law seems to be rather hypocritical, even sadistic. Attaching labels (aka "name calling") is divisive.
I believe the most important thing is that those who do wrong come to have the right view on the matter. That they acknowledge that what they did is harmful to themselves and others. A heartfelt apology and amends, when possible, should be made. All necessary life changes should be made so that the wrongdoing not only cease, but not happen ever again.
We can only hope Lloyd comes to his senses. Based on all reports, Lloyd is not taking responsibility for his actions. In the meantime, I know that the last thing you ever want to do to a person who is narcoticizing some sort of mental suffering is give them money. If they are hungry offer food. If they are cold officer them clothing and a place to stay. Do nothing to further their addiction.
