The world isn't a scary place. As much as there are animals such as tigers and leopards which could kill you basically instantly, they're predictable and at least you'd know what's coming your way. What you should truly be scared of is the unknown - humans. Someone with a bad mood could mean you never live another day. A stray bullet and you're done for. Some kid trying to go through a gang initiation and you could be the unfortunate victim. It doesn't stop outside, even in your own home - husbands killing wifes, wifes killing children, and children killing fathers. You can never really truly trust anyone. The world is a scary place. Maybe I watched too much gore in my formative years - humans are extremely fragile and a humans biggest nightmare is it's own kind
