Nope.
One common theme many of the WWII veterans in my old neighborhood tried to drive home with us kids…especially boys is that while it’s ok to finish fights once one is attacked(one has a right to self-defense), it’s NEVER OK to instigate them by throwing the first punch or otherwise physically attacking someone who wasn’t physically attacking you first.
Once one throws the first punch or otherwise instigates a physical attack/fight without provocation in kind, s/he is 100% culpable for the fight.
