Total a$$hole employer deserved to have his keys hidden

I worked for a doctor who was a total jackass. In every sense of the word. He was horrible to his employees and his patients. He was the bottom of the barrel doctor. His appointments were filled because he was the only one with openings. He would talk shit about patients the second they left, he would talk shit about us (his staff, running all aspects of his business). He would openly insult us in front of each other. Horrible guy. One day, he was in a rush and left his keys on his desk. Odd thing is, I didn't even think about it. I took his keys. Threw then in a trash bin in another part of the building. He was soooooooooooo mad. He was mad. I've never told anyone that. Kinda can't believe I did it, kinda proud of myself.
