@diablo: bit of an extreme situation, and one that would test anyone, regardless of their beliefs. Such a situation can only be handled as and when it arises -- any attempt to say "I would do..." whatever is unlikely to be more than wishful thinking.

For my part, what I hope I would be able to do, is to try to defuse the dilemma presented, anyhow I possibly could. The first priority should be to try to save all 30, but I don't think saving the 29 by becoming the killer of the 1 would be ethical.

anyway have to go, sorry can't finish now....
