Interesting statement. I can imagine LisaMarie's feelings as she sees how MJ's death played out.
It sounds like she has her issues as well(understandably) and if I'm understanding her correctly, they did have a "different" but real relationship, whatever exactly that was. It sounds like by marrying him, she was trying to help him, perhaps seeing the similarities (no way implying molestation similarities on Elvis's part, but rather the seclusion, prescribed drug addiction maybe) with how her father lived and died. She shouldn't however blame herself.
