It’s not like isn’t trying to fulfill the job he’s just coming up short. There’s nothing “moral” about this at all. The guy got hired to do a job, got an extension based (presumably) on performance, and now his employer wants to buy him out. Morality doesn’t have anything to do with it.

BZ, Wellman, and Manning provided negative value and were compensated greatly for doing so.
