Define 'worst'. Do you mean which country has the laws which allow the most irresponsible gun ownership (which is debatable), or the strictest gun laws? The strictest would be Greece, where anyone wanting a gun licence has to take a strict examination from a psychiatrist and a gun doctor, and about 19/20 applications for a licence get rejected.
What country?
Loosest.

Fairly and with strict adherence to the laws in your country.
It's up to your parents and the laws of the country where you live.
