Are sharks mean because they feel unloved, of do they just have a mean way of sharing their affection with others?

Sharks aren't necessarily "mean." It's just in their nature to kill. If they don't kill, then they cannot survive. It's just a way of life for them...just like lions and tigers and bears. Oh my!

Sharks aren't mean, humans are! Stop hating on the sharks! What do u have against them? Humans are evil! Sharks are perfectly friendly!
