Another reason I don't mind fighting (both literally and metaphorically) is because out of all the modes of ruin, it is one of the least unpleasant.
Life takes everything away anyway; you can't hold onto anything.
So I'd rathed throw it at my enemy as hard as I can, break as much of their shit as I can with it, than cower and clutch it for as long as I can as time picks it away from me piece by piece.
