Being left-handed isn't that unusual.
It might not be unusual, but I'm not sure whether we have enough evidence yet to determine whether left-handedness is a subtle form of evil or not.
From Wikipedia:
"Various innocuous activities and experiences become rude or even signs of bad luck when the left hand becomes involved. In some parts of Scotland, it is considered bad luck to meet a left-handed person at the start of a journey.[22] In Ghana, pointing and gesturing with the left hand is considered taboo. A person giving directions will put their left hand behind them and even physically strain to point with their right hand if necessary.[23] In some Asian countries, holding eating utensils in the left hand is considered impolite.[24]"
