People have been saying he was killed by irony
I'm thinking it's more than that
He loved guns so much he wanted children to watch gun deaths so they'd be used to the outcome
He wanted children to die so guns could go on*
He may have felt elation and joy that they got to kill him
Poetry
Poetry killed him
*and like all poetry there's a dark version where gun lovers will be shooting anyone that might have shared empathy (his most hated word apparently) with anti gun people
