Please note the legitimate; I'm not advocating whole sale executions of them, either. I'm simply saying that their own acts have removed them from the "precious" category. In essance, I'm ranting because that phrase is yet another of a million over simplifications that drive me insane.
Think about this:
"Why do we kill people who kill people to show people that killing people is wrong?"
To me, to kill someone who has killed another, is just as wrong as the killing the person did themeslves. Killing is wrong no matter what, in my opinion.
In addition, please consider the following bit of philosophy. All life ends. Death is one of the very few true constants in life. Life, in fact, is based in death. When we die, bacteria will consume us, scavengers may very well ravage us. The food we eat is borne of that death; plants are fed by the rotted remains of other living things. No form of life escapes the simple constant that for us to live, others must die. Death, therefore, can not be considered evil. It simply is. What remains is how we die, and what we do before we die.
And I do, but who are we to, essentially, play God and take other's lives? And yes, death is a part of life, trust me I know that. I came close to dying multiple times so far, and I'm only twenty-one. What I don't see, is the point of unnecessary killing. Pointless killing.
Sorry, I can't agree with that. Life is precious, I will agree with. However, saying all life is precious is going to far. Child rapists, terrorists, torturers, and similar ilk debase the value of their own life with their actions untill its nil. I'm not going to run around murdering them myself -- that would be just as wrong as their own acts -- but neither am I going to cry crocodiile tears because they got "what was coming" to them in a legitimate manner.
The only tears that I would shed, would be that they "had" to die, instead of being swayed to change what they've done.
