1) If you were aware that your opponent's wrist was injured, would you purposely use binds, to attack their weak spot?
2) If your opponent's leg was injured, would you prolong the active movement in each touch?
The questions are hypothetical, please answer them ithout regard to whether a given tactic would help you in a bout or not, eg Are you morally comfortable performing these actions?
I would say yes to the 2nd for sure, but about the first I am on the fence. It seems a little vindictive.
