There are a lot of people like that in the workplace when I worked. It is called kicking a person when they are down. Management had it as well which is why I got fired for getting sick on the job. Society in general hates the mentally ill. Every time there is a public shooting they claim the person is mentally ill and that paints all mentally ill people with the same broad brush. I'm non-violent and dysfunctional and could not do a public shooting. I have empathy and compassion that prevents me from doing something like that. The people who did the shootings are sociopaths that lack empathy and compassion.
