You can have pride in your newly independent nation and flagship cruise/ferry and still retain objectivity. Think about the conflicting interests. IF Sweden did know there was illicit cargo on the ferry, then it is clear the passengers were seen as collateral. If this came out, it could cause a massive public scandal, so decision is made to classify it and give the public a mundane cause. Sweden's rationale might reason it as thus, with Estonia being newly independent and Sweden as allies of USA keen to not give Russia an excuse to reinvade, that was the best solution all round. Estonia, suspecting of a cover up of the circumstances, is angry at the implied assumption it was all their fault. Whilst the maintenance and poor registration of passengers on board were all lacking, ultimately, if the sinking was sabotage (given the circumstances) the Estonians on the other hand have a motive to pass blame onto Sweden. It is not as simple as Meister wanting to protect the reputation of his country, because Sweden also needed to, if there was dodgy cargo on board giving rise to risk of passenger danger.
