Hmm, I think there's potential to go off topic here - lets try and avoid that because this is looking kinda interesting right now.
When I say off topic I mean discussion wether murder for whatever reason is wrong and wether that should be applied to those who destroy the planet with pollution and so on. That's a whole new topic in it's own.
I've always felt that murder for whatever reason is wrong. However I do believe that those with life sentences in prison should be given the option of a fast death via drugs or whatever.

I think this is the only time that murder might be an acceptable thing - but at that it's more of an assisted suicide than a murder.
My point here is that killing, war, murder are all pointless. It's argued that it's necessary but this is simply not the case. No amount of religous sanction can make that ok in my view - especially since those being killed are most likely not of the same religion as those doing the killing.
The upshot of this is that most religious laws are not needed, confine mankind and prevent improvement of society. However people still kill in the name of religion... this seems somewhat ironic to me.
On the other hand many religions carry with them some basic guidelines of what is good and bad, but these are simple moral agreements between most people and are most likely only included in religion to make them appear more accessable. The fact that Christianity wrote these into it's story in the form of the commandments seems quiet amazing to me and I'm suprised more people don't think that it was simply done to try and copyright the idea of these morals.
