The game included the ability to shoot the other player with no consequence - it sounds aggressive because "laser beam" but if you called it "tagging" then it would more clearly just be an in-rules option.
You're technically correct, but the football analogy switches context so that the meaning of aggressive is no longer bad.
I think the point bencollier49 is trying to make is that we simply gave software a specific set of rules to train it. It doesn't know how we perceive the actions it is performing.
The game could be described as two people eating poisonous apples in order to prevent the other person from dying. In that case, the currently greedy one would be the hero.
