He's sadistic (understatement), not the reincarnation of the devil. Just note that every one of the examples I gave someone did SOMETHING to offend him.

The peasants are peasants and don't really count as people. This is more a matter of raising than personality.
His family abandoned him and his sister rejected his attempts at kindness from a young age.

Although he goes out of the way to cause those pain a hundred fold what they dealt to him, he doesn't just walk around on the street randomly and stab people. I don't think he'd be in the guild then.

Of course, it is the GM call. He DID request sadism in a blood knight so I made him sadistic. Perhaps I went too far. :bow
