Can anyone who kills and takes another human being's life, especially in this way, be sane? I kind of always thought that someone who commits murder isn't right in the head and that they lack value for human life. A connection isn't being made to what they are really doing and they don't comprehend the depth of their actions.
Or, knowing humanity in general, maybe its completely normal and we're all doing our best to supress it 24/7.
And, yeah, I'm sad to see Dimebag go. That sucks.
