I felt the way you do, but it's funny what a 'great tragedy' will do to you. I had a abusive parent who then ran off when I was older. The first time I saw them in 8 years or so was when the police contacted the family and said they were in a hospital bed in a coma. I went because... well I don't know why but I never cried so hard. I have every right to hate said parent but yet I stood there and cried. I felt bad for them. Different to your deal but still sort of the same. Our emotions have a funny way of doing what we don't expect.
