On the other hand, I don’t think I could ever take the life of another human, but I’ve played characters who are cavalier about doing so. I’ve played characters who are much more confident than me. I’ve played characters who take bigger risks than i ever would.
That's an interesting observation RF from my point of view for the opposite aspect. In my real life I've taken a lot of serious risks, nearly been killed on several occasions and have suffered some severe injuries as a result. (My buddies used to call me "suicide." When you're a kid you don't think much about the consequences of such things, you get older and find it harder to move your skeleton around, and your wife says, "see there, I told you so..." and you start thinking kinda differently about your past. Still, it leaves you with a lot of good stories for the kids and grandkids and some fond memories.)
And whereas I always tell other people, especially in training, always be prepared, don't take risks without careful analysis and gathering all of the Intel you can, reconnoiter first then act, and so forth and so on (and I really believe that) - I have in real life often broken my own rules of operation and behavior.
But with my characters, in playing characters, I almost never take on any risk without trying to mitigate the odds as much as possible in my favor, no matter what I'm fighting. (I'll fight anything if necessary, but I want to fight with advantage and in such a way that my opponent does not anticipate my actions.) Yet in real life I'm much more impulsive. (Though that has changed some over time, because I'm not as young, fast, or reflexive as I used to be, and so I'm more cautious about survivability, or how to weight risk in my favor.)
I've never really realized it before because nobody has ever made me think about it in quite that way but over time I've become more like my characters. More like the way they've always operated. I used to be hell bent for leather at any worthy risk, now I'm more like, if I'm going into hell then I'm coming in through the back door nice and quiet. Sure, it'll take a lot longer but then again they won't see me coming.
I wonder if the way I played was always something sitting in the back of my mind as a sort of "psychological governor" or restrictor saying, "think about this a second boy before you start bleeding heavy again."
