A: Killing for no reason whatsoever is wrong to me. As far as that goes, I consider that an absolute. The idea of killing for the pleasure killing gives is morally reprehensible to me. But other circumstances, I'm not so sure. Mercy-killing, or euthanasia, in a situation where the killed has no quality of life, I consider a situation where it is very difficult to say 'killing is wrong' is an absolute. Therefore, my opinion is that 'killing is wrong' is not an absolute; there is too much ground for varying circumstances to allow it to be absolute.
Which comes back to moral subjectivity; real life cannot put every possible event into a moral code on day 1, there are too many variables. Therefore, not only are morals subjective, but they also evolve and adapt, changing depending on circumstances. What you may consider concrete today is quicksand tomorrow.
Q: How far do you agree with this statement?
