Growing up in a culture founded, I believe, on a flowering of remarkably enlightened notions that sought to bring balance between protection both from the tyranny of the individual and the masses, a system of laws before which all people would be tried for crimes at least in theory equally, it is natural, in my opinion, for individuals who have taken to the spirit of such a culture and internalized it, to hold in contempt, both the lawlessness of the law breaker and those impelled to resort to vigilantism to correct it, equally. This is because anybody with a thread of impartiality will recognize that the emotions generated by some crime to the rights of oneself or those who have one's sympathy, can cloud rational judgment and lead to new crimes cause by a lust for self justified revenge.I am a parent, and I think celebrating this death is wrong, but I don't deny my impulse to do so. I don't think @Moonbeam does either.
From a different perspective, I can easily imagine that the death and subsequent media exposure are more traumatizing to the victim.
The hardest part of advocating for this position is realizing that without his death, he could molest more children.
It becomes the duty, therefore and in my opinion, of any person enamored of the concept that such a system represents a significant evolution in human thinking, to want to protect it from the degradation that the simple carnal lust for blood justice represents. Sadly I believe our culture is in fact in the midst of the degeneration of just that very capacity to resist the rising cult of ego where most people lack the cultural and personal development on an emotional level to continue to support such a system. We live in an culture that is so filled with fear and the contempt it generates, and so corrupted by the buying of justice for those with money, that the vigilante has become the new form of cultural hero. And the day is coming when technology will advance to the point that some aggrieved individual somewhere will be able to take his revenge by destroying all life on the planet.
In a world where people had a real capacity to reason the mental health of the each individual would be top priority.
The reason we should strive to better understand what creates a desire for sex with children and then a willingness to acquire it ought to be to discover if it can be successfully and fully treated and if so how to inspire those so afflicted with the desire to seek such treatment. I don't know the answers, but I do know that the best that can be done at the moment is to insure that those who are so afflicted never ever have access to children. The desire to kill such people, understandable and natural as it may be, contains its own irony because it is pretty well known that a lot of people victimized as children grow up to perpetrate such crimes themselves. Suddenly those for whom we have the most sympathy become our most reviled? It's a fascinating switch that can be thrown to carry around in ones head.
