sniper mode, first I follow them and figure out their movements, next I find them and talk to them (I usually just stand there staring at them with a brooding sense of foreclosure and let them figure it out, if they get hostile I kill them then and there, otherwise on to step three), when done talking I move away and lie in wait, give them some time to sort things out, if they run I hunt them, track them down and kill without mercy, usually with an arrow to the knee and then an execution with my knife (or if I particularly hate them I just bludgeon them with my shield).
however if they choose to say their goodbye's and prepare for their death I let them, sitting in wait (out of sight naturally) until they are ready, then, before anyone knows what has happened, they are dead, with the familiar glow of an arrow returning to oblivion still floating around their head, and then it is as if they just dropped dead, like I was never there and there time had ended as if by the will of the gods.
killing your pray is all well and good, but it's nothing compared to the look in the eye of a contented man who has accepted their death and risen to the occasion, forgetting all their troubles and letting the world move on without them, joining with the streams of time for all eternity, it's the only glimpse of true happiness a killer could ever hope for, it's almost sad that such a beautiful light must be shrouded in death.
I pray that I will meet them again in the afterlife, hopefully in different conditions.
