That's the thing, yes. I'm all for casual guro, but the world still needs to hang together otherwise I lose any and all hint of suspension of disbelief.

A world in which people casually murder each other, and actually die, while not caring about that... doesn't work on any level at all. Evolution? Morality? None of it makes any sense.

Well, and I don't enjoy death. I'm not really into this for pain and degradation, either. I'm a bit weird, but who here isn't?
