Is people being violent until they find Jesus a common occurance?

[Drich]

Came across this curious video:
Another man who was apparently oh so violent until he found Jesus. Ben Carson reminds me of David Wood. To think I used to have some respect for David Wood (he is behind the Answering-Islam website). The video (linked below) is titled: "Psychopathic Atheist Turns to Jesus | Short Testimony of David Wood".

What I don't get is, David Wood was apparently a really studious Christian who, if I remember rightly, studied Christian apologetics at university. When he was at university, he managed to convert (the then) Ahmadi, Nabeel Quareshi to Christianity. Nabeel, by his own admission, spent a lot of time attacking Christianity, using all the arguments that he had been given by fellow believers, but was not prepared for how knowledgeable David was about the Bible. He even claims he had a dream with David in it and that dream is part of what convinced him to become a Christian (along with Quran 4:34, which he could not understand).

Yet David claims seems contrary to this (because he left jail around the time Nabeel said he become a Christian). He claims that he was sentenced to ten years in jail for 'malicious wounding' (since he attacked his father with a hammer). Does anyone know if this actually true, or whether he's just trying to reinforce confirmation bias in Christians? Even if he is telling the truth, I still consider his video to be dangerous as it's reinforcing negative stereotypes about Atheists (there are far fewer irreligious people in jails than Christians).

I found those who come to Christ on their own are those who have no dulusions of 'moral' superiority. Which most of the time means even by man's standard they/we are 'bad' people. (since the new standard on pop morality is based on hurting other people) it is more likly that one has to have hurt others to see themselves as needing salvation and seek Christ.
