Are sharks mean because they feel unloved, অথবা 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 শার্দূল and bears. Oh my!

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