I totally understand where you are coming from, I don't believe in "Luck" with my life or play. I believe skill, strategy, and action will get you far in play and real life. I also believe there is something more we cannot understand or see in our life, that is where prayer works. It may be positive affirmations, it may be nonsense, it may be real. I know in my life it has been something beyond my abilities or knowledge that has affected my decisions and those decisions of people around me in my life. I do not intend on forcing this belief on anyone, in fact, I don't believe it can be forced onto anyone.
With the above being said; we still have the right, even the responsibility (in my opinion) to care about these people that have been affected by this young man and his decisions. I will pray, I will treat my neighbor with respect and compassion, I will let my feelings about this event be known to anyone in my path. Will this change the world, maybe, someday. Will it change those that are affected by my presence, most certainly. Will it prevent the next incident of this kind? I doubt it. That doesn't matter to me as much as my feeling of doing all I can to make the world a better place for all who live here. So I will pray.
