Inflicting Harm by proxy and changing Hx

If a PC directly orders someone to inflict harm on another PC and they do it, does the other PC get more Hx with the first?

My gut says that if a Skinner or Brainer got someone to kick another PC's ass, yes they would, because that's how Skinners or Brainers kick someone's ass, more or less, but I'm more fuzzy on other situations.

If I'm your MC, you increase your Hx with both of them.

What about healing by proxy? "My dudes will take care of you" says the hard holder.

I would definitely do it for both in the case of harm, but not always for healing.  AW is a dangerous place, so there's plenty of opportunities to take Harm from external forces (threats), which means a Hardholder lucky enough to have an Angel could potentially gain a lot of Hx just in the normal course of play.  A PC causing direct harm to another, even using a third PC as a weapon, is a more momentous (and memorable) occasion.  Hell, I might be inclined to offer Hx if a Harholder refused healing, if doing so would cause Harm (if the PC was after 9 o'clock, for instance).
