Scientific knowledge versus spiritual knowledge

[robvalue]

I would say (sceptic) atheists would value life more if anything, as they think this is probably all they are going to get. This is 100% as far as a sceptic is concerned, but 0% as far as someone who believes in an everlasting afterlife is concerned.

To who is it going to be more valuable?

If I kill someone, I've taken their entire existence away, not just sped them along to the "real life". That's enough of an incentive in itself to respect the life of others.
