I see your point ballistic but it's such a leap for this man to make. Seriously, I can't imagine even thinking "well, ballistic had a couple pints at that party last weekend- therefore his murder isn't entirely unexpected".
I could see, perhaps, thinking "I'm surprised Johnny had that heart attack as he was often working out at the gym". There is, at least in passing, some possible connection between physical fitness and the element of surprise when a death is attributed to something that could be perceived as a result of lack of physical fitness such as a heart attack. Or, alternatively, I could see saying "I'm surprised Bobby died from Cirrohsis of the liver as he never even drank alcohol. However, there is absolutely no reasonable link between having a glass of wine and a smoke and murder.
So, my thought is that this man is using faulty identifiers as to who, on some level, "deserves" to be murdered. Bear with me on that "deserves" thing but I think you get what I'm saying. He has criminalized or demoralized two legal activties (drinking & smoking) as if they could possibly be a litmus test for good or evil ("deserving of death" or "undeserving" of death). Which is why, although he is not identified as a JW in the article, I'm putting money on the fact that he is either a JW, a study, or a sympathizer. Either way, I still think he's making a huge leap and using poor logic.
