What Adm. Denton and his fellow POW's held by the North Vietnamese went beyond heroic or even super-heroic, as were those men who survived Japanese treatment in WW II. Marcus Luttrell could be called a super-hero, but he would likely be the first to deny that what he did was heroic.
There is an argument going on today in the Toronto papers after a police officer was shot yesterday by a gunman trying to gain entrance to the courthouse in Brampton. He survived, but the bad guy is at room temperature. Now, the
discussion in the comments -- is the officer a hero who prevented a potential rampage, or was he just doing the job he is well paid to perform?
Having done "the job" for 21 years, I think he'd say the same thing that Marcus Luttrell would say. Others would say different.
