It really isn’t a matter of judging and flaming. Those choosing suicide have always been unable to have a Funeral Mass or to be buried on consecrated ground. It matters not one bit what his illness was. The part that matters is that he took his own life. It’s truly that simple. Life is precious. All life. That is why we, as a Church, condemn euthanasia, contraception, abortion, et cetera. He knew this, and still chose the way he went. The shame here is that the parish council, such as it is, decided to try to contravene Canon Law.
I understand that his family grieves their loss. No one would say otherwise. But to refuse to see that he took his own life, on their part, is folly, no matter what.
This may help to further your understanding of the Catholic view of what has transpired here.
