Serial Killers, Murderers and their Religion / Faith

It's odd that almost every religion has a vow which decrees "thou shalt not kill"; a pretty bog-standard easy-to-follow rule which at least 99.99999% of the people on this planet manage to keep to on a daily basis, even if some of us are atheists - and yet a recent study has shown that "people of faith" are more likely to be murderers than atheists - so does religion does play a big part in the life of many serial killers and murderers? Let's take a peek at who has what faith. 

As always, this is not a fully comprehensive list and I will be updating it as-and-when new data comes to light, but if you have any "accurate" information (with a link to a proven source), feel free to leave it in the comments section below. Thank you and enjoy. Mx
