I don't take offense. That is a highly brave action. The picture is so iconic that it even looks 'beautiful' even though it's very tragic.
But I don't see how it relates to free will. And it's unlikely I'll reconsider it since it's one of my 'specialties' for more than a decade! In fact I consider it a fact that both science and philosophy have proven, quite independently of each other, that there is no free will. It's just a remnant of our belief in the soul, basically. Once you understand that everything is material, and our brain is made of matter, and consciousness entirely depends on it, then the rest follows. Maybe a stone has no feelings and a human has feelings, but with determinism it's different: there is no sum that is greater than its parts. If material particles have 0% free will, then it doesn't matter how many of them you stack together and in what order, you will never get something that has 1% free will. There are some things that all material objects have in common, like having a position in space and time for instance. One of those things is being 100% determined.
There are famous free will experiments in psychology that you probably read about, but recently there was a new one (of the same kind) that a friend posted on fb:
