Your senses pulse red. You heave the massive bulk and let the weight of its metal substance cleave into the oblivious man's head. You feel an odd sense of rejuvination for the crime you have commited. A part of you wants to gouge a deeper hole into the man's head.
You stand there, your sweaty hands tightly gripped on the shovel. You regain your composure and the vile scent of the dead man leaks out the stairway.
You'd better get moving before someone notices the mess you have made.
