The Halo that would not light

I think the title means that the person who died never really got a chance at life so they never had a chance to do good to get their halo to light.
This poem is really sad. when i think about poetry this is what i think of. a poem with such strong emotion that it is obvious that it is the author just trying to make sense of what has happened in the only way they can.
My favorite line is "the spectacular catastrophe of your endless childhood is done"
i like the contradiction in spectacular catastrophe because even though the life was so short it was a catastrophe the child was here long enough for it to be spectacular to see them. :(
