Beautiful Blue Kangaroo
I understand that in modern society that most of you are sheltered sheep, but the truth of the matter is: Killing other human beings is perfectly natural, and if you had lived 800 years ago, you likely would have killed or been killed by another human being. Anyone who disagrees is a sheltered kid who was obviously from circumstances fortunate enough to avoid Military Service.
If not OP is very very dumb.
Yes humans are aggressive. Yes killing is something that comes naturally to us. But it isn't something humans are okay with doing to other humans usually. That isn't a result of being sheltered, it's the reason why in WWII the japanese and germans were made into caricatures. Because it's easier to kill someone if some part of your is able to say they are not humans like you.
It is natural to kill, We kill animals, most people don't blink twice. But kill a human, and prepare to never. ever. hear the end of it. Even if it saved millions of other lives. Especially if it saved millions of lives. Just ask Truman about those atomic bombs that was the only thing that stopped WWII before millions of citizens in japan showed the middle east how you really do suicide bombing to stop tanks.
Furthermore, use of ad hominem attacks on people who disagree is distasteful and points out how little you actually know.
