Silverfish Aggression

Silverfish are real animals (look them up, they are). But they're always hostile to players. Minecraft makes it a big point for any real-life animals to be neutral instead of always hostile, even polar bears. Silverfish, however, aren't neutral, and always attack the player. 

Silverfish could be neutral instead of hostile, and could only get mad if you attack them or break their block.

I believe that making the silverfish neutral would make more consistency within the game.
