There's a way to be honest without sharing personal details that aren't his to tell -- and those personal details that are his, Harold really doesn't want to share. He's too protective of his privacy. But he committed long ago to John not to lie to him, and it's a policy he's tacitly taken on with every traumatized ragtag killer who's joined their merry little band since, to good effect. He's no reason to change that now.

"I suppose I didn't, really. Ms. Shaw asked me to give him a chance and he's done nothing to cause me to regret it."

Over time that just becomes something more than a chance; it becomes a commitment. For Harold, at least. Trust is a big word and not quite something he'd apply here, not yet.
