^Indirectly, and Karkeys how is that the same?
Well, if you're just trying to play the game without pulling triggers (or pushing buttons, as it's a game), having a follower run along with you and operate the killing devices would work.
But if your goal is to not cause the death of your opponent, having your gal/guy/robot/doggie buddy do your dirty work for you doesn't absolve you of responsibility for what they do. You hired, or bought, or befriended them and brought them along, so you are responsible for the damage they do. You could send them away at any time, so by keeping them around, you are agreeing to them killing for you.
...Which is AWESOMELY FUN, of course, unless you are trying to roleplay the non-lethal character. It would be a fun mod to be able to choose a knockout punch option-- you'd have some time to run, but you'd have to fight the bad guy again on your way back, or they'd come after you. That would make for some hectic scrambling. :ahhh:
