I really feel for your friend Locke, that has to be extremely hard to go through. A couple months ago, a sort of family friend of mine died and I had similar feelings about the situation. This guy was not a good person. He had stolen, cheated, done all sorts of nasty drugs, lied, etc. He never did anything to me personally, but I saw the wave of destruction he caused throughout his later teen years and into his twenties. I felt the worst for his mother. His parents weren't bad people, but for whatever reason their son turned out to be a really bad apple, and their daughter got pregnant at the age of 12 and decided to keep the kid.
Anyways, he got diagnosed with prostate cancer and died a couple months ago, at the age of 27. He left behind three or four kids, a wife and an ex-wife. I felt terrible for his family, but knowing all of the **** he had done in his life, I couldn't help but feel that he deserved what he got. Which in turn made me feel like a terrible person, but you can't always help what you think. What you can help is how you act on your thoughts. I didn't share my thoughts or feelings with his family or friends, and I don't think your friend should share hers either. I agree with the others who said that if she feels the need to get things off her chest, she has you to talk to.
