I agree, it takes more to do it personally. I'm thinking a knife or strangulation is probably the most personal. Anybody could probably press a button or give an order for soldiers to wipe out whole villages without really thinking about it much, the disconnect is similar to being on the internet. Up close and personal is that little something special I mentioned earlier. Jack the Ripper, all the stranglers throughout recent history. I heard this hitman for one of the NY crime families talk about some of his "jobs" and how he'd prefer using a knife so that he could feel the moment they passed away! Some people get their rocks off on that kind of stuff.
