A misanthropic person does not like people and expects the worst of them. It would be misanthropic of you to say that every human being is a greedy, selfish liar.
The Greek word for human is anthropos and misein means "to hate", so to be misanthropic is hate humans, to consider them bad or wrong. Being misanthropic is more than just a bad mood, it's a way of looking at the world. Your misanthropic uncle, who has lived alone for decades and despises babies and kittens, seems to have taken a liking to you. This causes you some concern.
