[ He openly rolls his eyes at her and shakes his head. ]

I don't do this for you. I think you may be grossly overestimating the effort it takes for me to kill one of you. [ He turns and points at his would-be mugger on the floor, who is only now beginning to stir. ] For example...

I could crush his skull. Most direct - painless for him if I do it with enough force. Messy, but what death isn't? I would merely have to imagine something with enough weight or have one of my attacks dash him just so against the wall.

I could hang him upside-down and wait for the blood to rush to his head. Simple for me, but his screams may attract attention before he dies...

I could teleport him to the depths of the ocean where the pressure would kill him long before he could surface.

[ His gaze slides back to her. ] Or I could simply force his soul into the Underworld, thereby leaving a husk of what he was. I can go on but I suspect that's quite enough to make my point.

[ This doesn't even begin to cover all the vital organs he could simply rupture and leave to the natural process. ]
