Probably....unless your will is one with that of Heaven, as Morihei's was.
But didn't he say something like, "The art of aiki is to harmonize with another person to make him do what you want"?
And if what you want is to live in accord with Heaven and not be budged from that path, you only impose "your will" on those who want to move your will (through attacking you).
*shrug* As I said before, I haven't found that way of looking at things to be terribly helpful. If you'd like to indulge in semantic hair-splitting, feel free, but I'll pass.
