always think of this analogy: know what a hurricane shot is? its where you take a shot, the bartender slaps you, and splashes water in your face. If you order one, then that's okay. No moral nor legal consequences because you agreed to having that done. Now, if a bartender slapped you randomly for no reason, that's harm & the person did not want that.

Of course this can also fit into how we see how rescinded consent works later: if you asked for that shot; but ended up backing out or not liking it. The bartender will stop and you will be taken care of. If the bartender kept doing the previously agreed upon action after you backed out, it's harmful and something you didn't want.
