"I don't think the society is much safer now."

And your evidence for such a claim is?

What do categorise this 'dirty world' to be? It seems such an amorphous term; you compound this with words such as 'evil' and 'bad' - I think you should be more specific so we can get a handle on what it is you are actually talking about and worried about.

On a positive note, I'm sure your kids will be just fine.
