I think I'm giving up on Adventure mode for awhile. I started yet ANOTHER adventurer, do the usual proceedings, sneaking about, killing things with stones until I feel confident enough to take down my first bandit camp. I kill the ENTIRE camp with nothing but the stones I carried with me except one person whose legs and arms were broken from my rocks and I decide "He's laying on the ground, unconscious. I'll go bash his head in with my axe." As soon as I walk up to him, he wakes up, somehow dodges my swing, latches onto my throat with his TEETH and proceeds to kill me by biting my throat out. Yeah...
LOSING is FUN
Just think about the guy having his friends killed off by rocks and that he found the bugger who did it not only broke all his limbs he coming up for the kill/torture the fear of not moving and the fear of what you would do lead to him using his abs to roll past your attacks. Then with a final amount of effort lounge at your throat. Still you died but he's still immobile with all his friends dead loneliness plus lost abilities will creep in to the bandit and sooner or later he will wish for death, maybe at the hands of the next adventurer or from the bogeymen who will no doubt strike the lonely cripple.
The only human error from this is that you wanted to end is suffering up close than to just let the man bleed out or throw more items with a sharp weapon. well at least you learn something from that experience and won't attack someone sleeping up close unless you sure you can take them on awake.

Ill phrase a slightly different perspective.
Lying crippled on the ground, barely conscious, he waited, in pain, expecting death to come on swift wings.
As you approached, he saw his day coming too soon.
But, when you finally drew near, he came forth with a final rush of energy, sprung from the ground, and using his only functional limb tore open your throat, before falling back down, now in more pain.
As you thrashed about with your bludgeoning stone, he continued to try and crawl about...
