What if our theoretical person is responsible? Everyone is going to view any event like this with some sort of "self-absorbed" (I disagree with your definition of self absorbed here, but lets continue) response because they had some part in it (by your definition). The difference between a Depressed person and a non depressed person's response is the self deprecating thoughts. "Self Absorbed" has nothing to do with it.
