So if I kill a teenager for threatening my family, can i tell the court my conscience is clear, that's life, so get over it? I was just using my survival instinct of protecting my family!
Somehow I don't reckon that will wash because we as humans are civilised and we know right from wrong, as a highly intelligent animal we are responsible for what we do. We are unique. We are the only animal that laughs, we are the only animal that has sex for pleasure and we are amongst the very few that kill for pleasure. We have a conscience and some of us have very different values/personalities/likes and loves to others and we have the ability to respect others for that if we choose.
I will now consign my soap box to the back of the cupboard again. My high horse has been lowered. Any my ivory tower has been dismantled.
