I believe strength is only relative, what's truly important is knowing how to harness it. In simple things like lifting boxes or such other menial tasks I'd say that I'm fairly capable to lift things up to a few hundred pounds in weight without much effort; but I don't much care about menial tasks, I care about violence. This is where knowledge, and a good deal of experience, comes in. I'm very efficient when it comes to fighting, and potentially deadly, even unarmed. As far as the discussion about killing goes I'd have to side with the ruthless, cold-blooded killers, though this could only be my misanthropic side poking it's evil little head out. I don't place much value in life in general, if anyone reads this and is hoping for a slightly more detailed (yet still pretty damn vague) reason.
