It seems to me JRRT used "hope" with 2 meanings. And Admir may have been lost by a man (elf, hobbit), but if Estel was still there, the actions were still proper.

 'Have ye then no hope?' said Finrod.
 'What is hope?' she said. 'An expectation of good, which though uncertain has some foundation in what is  known? Then we have none.'
 'That is one thing that Men call "hope",' said  Finrod. 'Amdir
 we  call  it, "looking  up". But  there is  another which  is founded deeper. Estel we call it, that is "trust". It is not defeated by the ways of the world, for it does not  come from  experience, but from our nature and first  being. If we are indeed the  Eruhin, the Children of the One, then He  will not suffer Himself to be deprived of  His own, not by any Enemy,not even by ourselves.
 This is th last foundation of Estel, which  we keep even when we contemplate the End: of all His designs the issue must be for His  Children's joy. Amdir you have not, you  say. Does no Estel at all abide?'

 and from more modern times, best illustration is Sam. There is no Admir with him any more -he knows there is no returning for him and his master anymore, but Estel (that is Trust in the Ultimate Good) gives him strengh to go on and conquer despair.
and edit:
How came Morgoth adn Sauron were evil?
the root of all evil = pride
pride = puttin oneself above all the rest = trusting one above all the rest
Trusting one above all the rest = Not trusting (or trusting less) Eru (the Ultimate Good)
Not trusting Ultimate Good = rejecting it
Rejecting Ultimate Good = being evil
