Who gets to decide who is stronger, weaker, aggressor and victim? The strongest.
To the degree being seen as weak is advantageous and valuable, the strongest will claim that status for itself. It will defend its claim. And when it speaks truth to power, it will respond with overwhelming force if its powerful oppressors respond with insolent back talk.
The first will be last, and if try to stop them you will be crushed like an ant.
