ag·gres·sionNoun/əˈgreSHən/
1. Hostile or violent behavior or attitudes toward another; readiness to attack or confront.
No. Taking someone property without permission is aggressive.
"Taking" requires energy, hence some sort of force.
Being "hostile" or "violent" behaviour requires force and energy.
How did you come up with no here? Weirdness.
The answer is
YES; it is measured in Newtons of force. Your misunderstanding about the characteristics of aggression is fly-by-night seat-of-the-pants stuff. Any attitudes about the specific attributes of the nature Force(s) doesn't change the forces themselves. For that matter, any which way I think about it doesn't change the fundamental characteristics of any physical material matter or any phenomenon related thereto. Thinking differently doesn't change anything about how the Universe operates.
The only way I change stuff is by physically interacting with it, and even then only to a limited extent.
