I think its just that he knew that violence only brings on more violence, and once unleashed our animal blood lust can find it hard to control. I've seen it too many times to doubt it. Normally passive peace loving types can be pushed to the point where not only do they commit great violence - but, and I think here is the problem, they LIKE it. Its something that once unleashed can be hard to get back into the bottle.
Back when I was a little kitty kat I was pretty much the geek. (I'm old so this is pre-computer) I wasn't just the captain of the audio/visual squad, I WAS the audio visual squad, which was swell, as old Father Drinksabit and Sister Allthumbs could never get that stuff to work and I got pulled out of class all the time to help. As things went along I fell in with a bad crowd, rock band people, and I began to back my car up on Friday afternoon and load it up with stuff and do this very psychedelic light shows in the area. I also knew how to fix electronic stuff, so I got in pretty good with this bad crowd.
This has a point, having to do with bullying, so stick with me here.
There were two main groups of us who ended up doing a lot of this kind of work. Geeks like me and big tough guys who could carry Marshall stacks, one under each arm. Because we had three things in common - drugs, sex and rock and roll - we formed sort of a partnership. The geeks taught them about all the gear, how it worked, and a bunch of physics/electronic stuff they had not bothered to learn in school. They in turn taught us how to get in shape and how to do great violence to other humans, which they were very, very good at.
If you have ever seen, as I have, that kid who has been picked on, bullied, and all that get over on someone else in a fight for the first time in their life, its true shock and awe. All those moments from the past come flooding back, every punch, hit, kick, wedgie and Indian burn, every time you got pantsed and tossed into the girls room, every time you're books were thrown into a puddle and your homework was ruined - every single slight you ever took from the bully types is now going to be repaid in spades. More than once I've seen little geek types (and had it happen to myself a time or two) had to be pulled off because they were about to kill someone, there was that much violence unleashed.
Now I can't say these jerks didn't have it coming, they did. Still, perhaps it was not the best way to go.
It is very empowering however.
