Seven members of the Aum sect were executed

Most people praise Japan for its brilliant technology, culture, diligence (I myself also) that it is a developed civilization etc. Exactly ! I also appreciate the fact that Japan uses the death penalty for deliberate, planned murder because not only the developed technology and other factors mentioned above constitute a civilization. This is a brilliant argument against opponents of the death penalty. Every developed civilization has in its values the death penalty for murderers. Currently, Europe is lower than Asia not only in economic terms. For example, In Great Britain, the court allowed the murder of a sick child. Europe must return to the values that constituted its power.
I suggest you start from Poland.
