Sorry for the late reply, I forgot about the existence of the forums. The new layout works that well. Also, I should be using quotes, but I don't know how to, and I won't learn how to use the functions of a forum that I'll forget about again within ten minutes. The new layout is that awesome.
People aren't as equal stuff: Yeah, they aren't, and they never were. Law and other rules and authority might try to handle them (us) as such, but one thing that simply never did or will exist is two human beings who are equal. You can only force a kind of equality on people if you have a very limited view of things.
Killing is bad: Yes, I think so. But it's not bad because I don't want to be killed in return, it's bad because hurting others makes me feel bad. That's empathy, which you quickly threw in and threw out, but it is a much more important part of a human being than anti-murder laws, simply on the basis that it exists as a human trait. Even the cavemen felt it; it's a part of human biology (at least I'm fairly sure that empathy has biological roots). That's why I don't kill people, and not because of some cold logic about not wanting to normalize murder.
So yeah, killing is not bad because it is bad, but because it makes me feel bad, which is a much more legit justification for not killing than any kind of law or logic or ultimate goals. But, as empathy is a natural urge, it can get suppressed, deteriorated or held under conscious control, like other natural urges, hence people do get killed. And then the phone rang and I forgot how I wanted to finish my post. ****.
