Is beheading more humane than long winded chemical and electricity executions?

I do not agree that, mistakenly, executing innocent persons promotes the greater good of society.
I didn't say that, of course. Of course you did. Of Course not.
OK. In that case I don't see what your objections to the penalty are. 1) we could do the killing humanely if we wanted to (interesting that we don't) And if we sometimes killed an innocent person it would still be for the good of greater society overall.
Why are you denying you said what you said? That's very silly Darron. "It" doesn't refer to the killing of innocent people. It refers to the overall thing, the killing of guilty people less the cost of some mistakes. Of course I wasn't saying that "executing innocent persons promotes the greater good of society". And actually I was only suggesting a logical conclusion following from what Tim said, not a reflection on what I believe at all. You are a very poor communicator. You write something that is perfectly clear, then need to come back and explain why what you wrote is not what you meant. Online forums are not face-to-face conversations and require different communication techniques. You cannot assume people will be able to read your intention without proper context and explanation.
