“If you want to know what a man's like, take a good look at how he treats his inferiors, not his equals.”

Apparently this quote is from Sirius Black. I was sure that those words were said by either Hermione or Dumbledore...I guess my knowledge of Harry Potter is not as good as I assumed.

But basically people who support aggression/war on other countries/ individuals or the scum who torture animals are not a good people.
