What is it that your characters value most? As with me, it is highly unlikely to be just one thing, but you should be able to deduce which your characters would fight for and which they wouldn't. It should also be apparent why they would feel this way.
It can be useful information for an enemy, of course. What can they use against your heroes here? What does the enemy value that could be used against them? (It's never a one-way street in fiction but you can exploit that).
See this as an invaluable part of an outline and have fun working out how you can use a character's values to strengthen their portrayal and against them to generate conflict.
