I think that, perhaps, the right word there is not "willing", but "pressured".
And someone who is pressured into doing something is not playing on a level playing field. Then add in the probability that the person was surprised by events (a sneak attack, if you will). So, yeah, that person really was being victimized.
But I didn’t say ‘pressured.’
I said ‘willing’ and that’s a
difference between victim and non-victim.
