The hallway fight

You grab the machete and hack at the short man. While this is happening the big man runs towards you. You grab the second machete and throw it at the big man. The machete hits him and knocks him back causing him to hit his head on the wall. You now have the chance to seek the revenge you deserve. The man that killed your parents is now scared and pleading for you to stop. Will you seek your revenge or spare him?
