Speaking about morality that comes with religion, especially organized catholic religion headed by the pope .... let's take a look at some unmentioned realities of that morality
You can't have a coin with only one side.
The Vatican that still claims to be a force for good is staying silent because it is seeking a concordat with a state that still has a KGB and statues of Lenin on its streets, just as it sought accommodation with Nazi Germany in the 1930s.
The advantages for the papacy are hard to judge, because the terms of concordats are secret, but we can assume it wants what it has always wanted: public money and control of children's schooling. The advantages for Lukashenko are easier to grasp.
It is an error to suppose that dictators do not need to worry about public opinion. At a minimum, they want to secure the passive acquiescence of the subject population and to demoralise their opponents. In return for agreeing to cut a deal with Rome, a grateful Lukashenko has heard Cardinal Tarcisio Bertone, the Vatican secretary of state, do both.
