This depends on a person's mindset and upbringing. I agree that deep down some where every one feels and accepts the existence of some one who is looking over us, that is good because that creates sense of security and confidence, but the level of trust is different for different persons.
That 'somebody' (God) looking after! whom. He looks after crocodile and fish both, tiger as well as lamb. I don't understand how fish and lamb can feel security from an entity, who is 'equally fair' to crocodile and tiger. False trust helps nobody.
This is natural, god has made food for every one and then nature is run by balancing. You see if these animal wont live and eat the way there were made to act, this earth would become overloaded. That is law of nature, God has nothing to do in that, although I am not a blind follower. I love only nature or Durga maa.
