Serial killers can be likened to viruses. Whenever they are discovered, they're evidence of something gone wrong. They symbolize a society on the fritz, so to speak They've also always been here, probably always will be, and they are ever-evolving. However, it might also be a misconception to call them "viruses," "monsters," or even "evil." The most startling thing about serial killers is that they are actually human. When we exaggeratedly try to separate ourselves from them, we're sort of kidding ourselves.
As forensic science advances, one can imagine technology solving more and more crimes. It's not crazy to imagine crime-solving “apps” used on a large-scale basis, even on cold cases. Nevertheless, not every country is known to be advanced in solving crimes, and even so-called "developed countries" get it wrong, or let cases go unsolved.
[Note: I am not a professional metal historian, nor a huge metalhead. However, to the best of knowledge, this information is accurate—also, sometimes even huge fans get facts wrong, so I wouldn't be alone in that regard if I messed something up.]
It sounds bleak, but let's face it: There are so many ways to die. It can require mental skill and determination to not be afraid. One of the ways one could go? Death by poison. It's one of the oldest tricks in the book, actually.
A tune is rarely 100 percent original, for better or worse. For example, Mogwai's tune "Sine Wave" is very similar to "A Warm Place" by Nine Inch Nails (NIN), which is itself similar to "Crystal Japan" by David Bowie. The question is, is this kosher? I don't mean to be the "music police" and tell artists what they can and cannot do. For the most part, I am not offended by something being a bit derivative. What matters most, in my books, is simply that the "homage" is successfully done.
We live in a troubled age, and how we treat music (and musicians) reflects that. I won't say musicians are always treated badly, but they are often chronically overlooked. Unless they're created by corporations, for corporations, they'll probably struggle to gain exposure for their craft. Great bands go largely unnoticed, then largely fade away.
