Our reading
An editorial interpretation.
The speaker replaces a flattering definition of heroism with a grim claim about causing other people's deaths. Offering to let the listener look it up makes this bitter judgment sound like an ordinary dictionary fact. The confident delivery gives the reversal its dark humor.
