My post isn't an instance of blaming the victim. In my post all I did was note that in order to exist as a victim, a victim has to present some sort of obstacle for the bully. In some cases the victim has a particularly active role in maintaining his condition; in others, the victim plays a more passive role. Whatever the case, the victim always does have some measure of responsibility, even if it's merely by choosing to prolong his life. I wouldn't call a victim guilty, though, unless he chooses to turn his bullies into victims themselves. In that case he makes a choice that is seldom positive for anyone involved.
As an aside, please do note that when I use the word "victim," I don't mean a victim of random violence. When I use that word I mean someone who has an ongoing history as someone's victim.
