Death

I'm confused, everyone is going to die sooner or later so what is life all about? Is our life set in stone or does it change by our actions. Do we determine our future and whats going to happen to us or is every move destiny? I constantly ponder the question, "Why do good people die and why are bad people given life?" I don't mean to say that bad people don't deserve to live, i just cannot figure out why God put people such as Hitler or Saddam on this planet. Maybe there are special purposes for these people, I just cannot seem to understand them. Even though Jeremiah Johnson's death was a couple weeks ago, I cannot seem to get the fact that he will never again take a breath of fresh air. His life was cut short in a freak diving accident, and thinking about it makes me feel horrible. I never actually had him as a teacher, but seeing the faces of those who he impacted, I knew he was a great man. The suddenness of his death opened my eyes that ANYONE could die at any moment. I should take every moment and breath as well as interactions with people as if they could be my last. I wouldn't ever want to regret anything I said or did if a person were to leave my life.
I don't fear death because it happens. The reality of life and how precious it is leads me to understand it more. Never regret anything you do, just live the life you want to live and enjoy every second of it.
