Jimmy Akin raises a serious question here. There’s odium fidei (“hatred of the Faith” by those killing you), and then there’s “turn the other cheek.” (Although this doesn’t preclude defending yourself first, as the list of kingly Welsh and Saxon martyrs tends to testify.)
OTOH, as a non-canon lawyer and a member of the faithful, it is my job to be part of the sensus fidei, including the early veneration and acclaim of martyrs. And my sense is that the man is a martyr.
Also, I have petitioned Fr. Hamel privately on several small matters, as is the right of any of the Catholic faithful when anybody passes, and thus I have received several small (but important!) favors from the Lord through his intercession. So yup, my personal opinion is that God also says he’s a martyr.
Now, whether or not this is recognized soon is another matter. Rouen was the site of the death of one of the Church’s greatest saints, remember, and she wasn’t canonized until World War I. So I can wait.
But I’m pretty sure I know the answer.
And if I were someone in France with a bad disease or disability, I would hie me to his funeral and try to get near his coffin. Because martyrs are really good at taking care of that sort of thing.
