Why wouldn't you run? There's nothing lost in the attempt. If anything, it would be out of character for him not to try, as that would mean the orc gave into despair.
There's actually a fascinating psychological concept related to this. It's called [url=http://en.wikipedia.org/wiki/Learned_helplessness]learned helplessness[\url]. So, yes, after 600 years I would very well expect him to stop trying to get away. Unless, of course, his memory was being chronically modified in order to avoid despair.
