It is apparent that Violet is not a divine being, she cannot control the minds of people, but can only guide them.
This is not a bad thing, because Violet can be very sure that the enemy she is facing is indeed a villain.
Her intention is merely to inform as many people as possible, through simpler means, that this person is a villain.
There is no other malice, and certainly no intentions of manipulating others for vile purposes.
She just hopes to guide the public to see what she wants them to see.
And that is precisely the crux of the matter.
It involves the risk of both accurate and erroneous perceptions.
Everyone is clearly aware of what such a risk implies.
So, they adopt wiser actions and choices. Even at the end of his life, Halse could still maintain a cool and clear mind, and make the right choice.
It must be said, this is a strong woman, she is cool and determined, proving to be a worthy adversary.
