You acted unprofessionally and pretended to be your employees friend and confidant. Then used the information you gleaned, NOT their behavior at work ... to get them fired. That is YOU ABUSING your POWER, like the little Nazi fuck you are.
You're nuts. I've had people express their racist viewpoints to me completely unsolicited. We could be talking about a football game, for example, and the scumbag will say something like "did you see how that dumb n-----r got intercepted on the one yard line?" For some people it's so ingrained they don't even think before talking.
