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

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 believe that regardless of religion people who are violent will be violent. I never had any religion in my life and iv never been a violent person. That being said, a certain friend of mine has a ridiculously devout Christian family and his father beats his mother.... Religion only has that type of influence if you let it.
