No matter what you BTC can be stolen.

Well, that is indeed true.

Even for a paper wallet, your wife or your son could stole it from your safe (if they know your safe's password).
And for offline wallet, they could stole your whole HDD (if they know your wallet's password)

You could make multiple cold storage wallets with different passwords and store them in different geographical locations.

Obviously they can be stolen but it's only cause you would've done something wrong if that were to happen.
