You should care about BOB, but he certainly does not care about you. BOB was trapped in a SCI-FI science lab, by sentiment-powered robots to study its careless behavior. BOB did not care. One day BOB leaves the lab, just as a form of distraction. Chased by hearth broken robots he carelessly slaughters them using some prototype weapon that is scattered in the chest around the lab. Not caring about the proper utilization of those weapons, BOB just improvised some powerful moves, killing as many robots as he can with a single shot, and then leaves the weapon behind.
