I felt this way at first, but not after reading the entire post. Yes, it was emotionally driven and certainly goes against a lot of rules for job solicitation.
But I actually think he's shown himself to have good character here. He isn't attempting to sabotage the company even though he could. This happened very recently so you'd expect some of the emotions to be raw. I don't think this person is "high risk" if firing them after abusing them means that they're still loyal enough to you to not reveal your identity publicly. It sounds like this person was a trooper right up to the very end and is in fact pretty much the opposite of high risk.
