Bravery / courage - is acting.. even though you *are* afraid - ask millions of ex-GIs et al.
I don't know what to call: acting under religious conviction of the level which devalues all life and all society - for one's personal fantasy of a God who wants You to ____. Sociopathy is one partial-definition. Others overlap. There is no 'fear' - because there is no thought or feeling - mechanical action after those have been purged.
Nothing about courage, bravery IMhO.
