I ran across a case not too long ago, where a man who had been invited to a private party, after consuming quite a bit of alcohol, insisted on jumping into the host's swimming pool from the roof of the host's house. The host asked him and asked him not to do it, but he persisted anyway and jumped. The inevitable happened: this man is now a quadraplegic -- and sued his host for not stopping him. In the end the courts found that the host was 40% liable for the man's actions -- and so was responsible for $2.8 million of the eventual $7 million insurance settlement. (Pulling numbers from memory here, so they might be slightly off.)
Those in the Western world (and in the United States in particular) live, currently, in a victim mentality: in which all must shun any responsibility for their actions at any cost. (Hence also the increasing number of lawsuits.) There is a very deep reluctance to say, "I caused this. I, and no other."
What is it that makes people so very eager to take on the role of victim, to shove responsibility for their own actions onto others? Why this inner need to see oneself as powerless?
