Translation: I'm a horrible human being. All civilizations have murdered each other and waged war against others since the dawn of humanity but that doesnt excuse it still going on. Also human life is priceless. Old rocks can always be carved again or replaced. Lives cannot. Rocks have no value other than what humans give them. They're just rocks at the end of the day.
I've made a perhaps cynical translation (simplification) but that doesn't mean that I agree. BTW your insurance company can tell you the exact price of a human life

.
How can a company decide the value of one's life???
It takes a lot of time to grow, and people like these just don't even think before killing anyone, they don't see that if the ones they are killing are having red blood, then their own blood is also red and God has made everyone common, so why these f*cktards discriminate, and BTW who the hell are they to do that???
